bug#43166: The issues.guix.gnu.org is hard to read in emacs-w3m.

Hi Mark,

It does indeed wrap each line, because otherwise we can’t style the
lines e.g. to highlight additions with green and deletions with red.

People who use Emacs anyway will have Emacs apply its own fontification,
so that’s of no use to them.  But people who use Emacs would probably
want to use the Emacs interface to Debbugs anyway.

The extra spacing between lines as seen in EWW is not intentional, and I
did not see this in my local tests.  (Perhaps different patches render
differently in EWW?)  I’ll add this to my TODO list.

Note that you can also view the raw messages.  Every message part has
its own link; following that link you can see the unstyled plain text
rendering.

There’s nothing wrong with the sample HTML you posted.  Yes, mumi’s is
more verbose than just wrapping text in <pre>…</pre> because we need
more markup to tell browsers how to style the patch.
