[PATCH v2] docs: process: email-client: add Thunderbird "Toggle Line Wrap" extension

[PATCH v2] docs: process: email-client: add Thunderbird "Toggle Line Wrap" extension

[Vincent Mailhol]

While reading the git-format-patch manpages [1], I discovered the existence
of the "Toggle Line Wrap" extension for Thunderbird which I found rather
convenient.

Looking at the history, the ancestor of this extension was added to the
documentation in commit e0e34e977a7c ("Documentation/email-clients.txt:
update Thunderbird docs with wordwrap plugin") but then removed in commit
f9a0974d3f70 ("Documentation: update thunderbird email client settings").

Extend the paragraph on Thunderbird's mailnews.wraplength register to
mention the existence of the "Toggle Line Wrap" extension. The goal is not
to create a war on what is the best option so make it clear that this is
just an alternative.

It's a practical alternative, I see no issue.

I also use this extension and find it useful, good to have it documented.

Btw, there are some tricks for when you want to wrap parts of the mail,
and leave other parts unwrapped. Useful when drafting a reply that
contains code snippets.

I don't remember the exact steps, but if you know it then it's good to
have it in here as well :).

This got broken quite a while ago: You could enable line wrapping, mark
the paragraph you wanted to have wrapped, select "rewrap" from the edit
menu, and then disable wrapping again. The used to leave the marked
paragraph wrapped-around behind, but not anymore. If there is a
different trick by now, I would be all ears as I used that very often in
the past.

BTW, if you want TB to have better wrapping support natively, please
jump on https://bugzilla.mozilla.org/show_bug.cgi?id=1587153. We either
need to convince them of that or at least finally get an add-on API so
that I do not need to permanently bump the supported TB versions (see
https://github.com/jan-kiszka/togglelinewrap/commits/master/). With the
API Experiment that is still needed for toggling, I'm not allowed to
declare the add-on as compatible with future TB versions.
