This was brought to our attention by attila_lendvai on #libreboot IRC.
Essentially, the previous instruction was vulnerable to potential collision
attacks.
With this new instruction, it should be a bit safer.
Since this is urgent, no pull request was issued. This has been committed to
the repository directly, with consent from and_who on IRC.

* 'pre' blocks and tables use scrollbars if the viewport is too narrow
* Code content which is not within a 'pre' element wraps automatically
* Code content and 'pre' blocks have a gray background color
The added background color has two purposes:
* The left-margin for pre blocks is removed, because it consumes too
much space on narrow viewports. However by using a background color,
the reader can still recognize 'pre' content as code blocks.
* Code content which is *not* within a 'pre' element wraps
automatically now. The background color allows the reader to
recognize the "connection" between automatically splitted lines of
a single code element. This way, nobody will mistake a one-liner for
a multi-liner.

they're not the first libre OEM, but they are the first one to produce libre
hardware that is also high-end (IBM POWER9 competes with Intel on performance)

this concerns an entry on the suppliers page, for a product from my own
company. Pull request therefore not required
I've decided to take D16 off of minifree, in order to reduce competition for
the TALOS II product that Raptor Engineering launched today. The world needs
libre OEMs, and Raptor Engineering is the first one.

It turns out that we only need bare HTML files for .md files in news,
yet publish.sh creates them unconditionally. That is, we spend a lot
of time building bare HTML files that we never use.
This commit makes it so that bare HTML files are only generated for
news files, which speeds up the website build significantly:

Unlike what the comment says, the target .md.html does apply to
news/index.md (it's just that news/index.md must be generated first
by index.sh).

When running "bash -x publish.sh index.md", the following happens:
+ pandoc --smart /tmp/libreboot_www.Xne7SYgf4e -s --css /global.css '--css /headercenter.css' --template template.html --metadata return=
pandoc: unrecognized option `--css /headercenter.css'
Try pandoc --help for more information.
This is because the OPTS variable is being quoted, which causes its
value of "-css /headercenter.css" to not be split on word boundaries,
that is, spaces. Because pandoc has a "--css" option, but not a
"--css /headercenter.css" option, pandoc expectedly complains that
said option does not exist.
To fix this we just unquote OPTS, and add a shellcheck ignore directive
so this won't be reintroduced in the future.

Splitting rss() into 3 smaller functions allows factoring the for-loop
out of rss() This is done by having the new rss_main() function take an
argument instead of operating on a global variable, as rss() did before.

I find it easier to read this file if all function definitions come
first, then all the actual stuff we do comes at the end.

It makes the code easier to understand than the global variables that
were used before.

When running index.sh on OpenBSD, the following error happens for
each item in the news/ directory (output is from "bash -x"):
+ touch -d '4 Jun 2017' news/andrew-robbins-new-maintainer.md
touch: out of range or illegal time specification: YYYY-MM-DDThh:mm:ss[.frac][Z]
This is because OpenBSD's touch(1) requires that the "d" flag's argument
be in ISO 8601 format, that is, "YYYY-MM-DDThh:mm:ss[.frac][Z]". This
could have been dealt with by converting the article date (determined
by "sed -n 3p $f | sed -e 's/^..//g'") to ISO 8601 format, then passing
the date to touch(1). That would have required even more code, so was
discarded as a possible solution.
Instead, we solve this by keeping a MANIFEST file under news/, which
is read to determine (a) which articles should be added to news/index.md,
and (b) in which order. This avoids the need for touch(1) altogether,
finally making the whole libreboot website build properly on OpenBSD.
This also allows a minor simplification in the Makefile.

When running index.sh on OpenBSD, the following error happens for

the date to touch(1). That would have required even more code, so was
discarded as a possible solution.
Instead, this has been solved by prepending the ISO 8601 date to the names
of all news items. This has the benefit of avoiding the need for touch(1)
altogether, as a lexicographic sorting of ISO 8601 dates is the same as
a date-based sorting. In other words, "ls news/*.md" will give a list
of articles sorted by date, which we can then append to news/index.md in
that order.
One downside of this solution is that it introduces the possibility that
the date in the filename (ISO 8601 format) of a news article does not
match the date inside the article (e.g., 1 May 2017). I have not dealt
with this as it remains to be seen whether it will be a problem in
practice.

This is the same idea as 497a49162f7c8b5c1d7c653087b0ac6c8e5765f9.
Without this patch, the following errors occur when running index.sh:
sed: 1: "news/new-mailing-lists. ...: extra characters at the end of n command
sed: 1: "news/andrew-robbins-new ...: extra characters at the end of n command

Before the Makefile, publish.sh was executed on markdown source
files using find(1), which happened like this:
./publish.sh ./index.md
Now that we have a Makefile, this happens instead:
./publish.sh index.md
Note that the file argument "index.md" in the first and second case
both refer to the same file, yet they are different strings. This is
important because publish.sh gives index.md (among other files) special
treatment, and it does this by string comparison.
Unfortunately, only the argument in the first case ("./index.md") will
cause publish.sh to give special treatment, while the argumnent in the
second case ("index.md") will not.
To fix this, make it so that both "./index.md" and "index.md" trigger
publish.sh's special handling. This commit also fixes the same issue
for "docs/fdl-1.3.md" and "conduct.md".

This is done by replacing www/generate.sh with a Makefile. Benefits:
- Makes builds incremental, meaning that only the minimum number of
markdown files will be converted to HTML during a build. The previous
scheme always generated a new HTML file for every markdown file,
which is a big waste of time if only 1 or 2 markdown files have been
changed.
- Allows for much faster builds through concurrent jobs (e.g., via
"make -j4"). On my 4-core machine, my average build time for the
website with generate.sh was just over 26 seconds; with "make -j4",
it was 13 seconds.
- Avoids portability issues with find(1) in generate.sh, which I was
encountering on OpenBSD.
A note on portability: unlike GNU Make, OpenBSD's Make does not have
the "$(shell [commands])" construct, so we don't use that. Instead we
use "!= [commands]", which is supported by both.

Instead of always using the same file (temp.md), use a unique temporary
file so that multiple instances of publish.sh do not clobber each
other's work.

On OpenBSD, publish.sh errors out at the following call
to sed(1) (from "bash -x publish.sh"):
+ sed temp.md -i -e 's/\.md\(#[a-z\-]*\)*)/.html\1)/g'
sed: 1: "temp.md": undefined label 'emp.md'
It seems that "temp.md" is being parsed by sed as a sed command,
not as a named file. This is likely due to OpenBSD's strict
usage requirements for sed:
usage: sed [-aEnru] [-i[extension]] command [file ...]
sed [-aEnru] [-e command] [-f command_file] [-i[extension]] [file ...]
As shown above, the sed command must always come before any named
files. This commit does that, which fixes publish.sh with OpenBSD's sed.
This is also tested and working with GNU sed v4.2.2

OptiPNG losslessly optimizes .png files; in other words, the images
in question should (and do, by my testing) look the same.
In short, we save some bytes for free.

Be consistent with marking up commands as such, so the documentation
is less surprising.

This is mainly useful for being able to run these scripts on BSDs.
And for users who use a Bash not installed to /bin.
