Pardon me, I think I missed that mail too, and caused you to loose time
because of that (given the relatedness of many conversations now) :/
I really should read all emacs manual, I even have it printed…

Thank you!

Thinking to it, yes, a paragraph is the most meaningful semantical unit to
do that. I guess in any file where lines can be filled (like, except csv
files for instance) there wouldn’t be sense to do that…
…but I thought the definition of a paragraph was contextual, and determined
what M-q would do… but here I notice it isn’t: it’s barely “any portion of
text separated by a blank line”, so many bullets within org-mode (whose
each would be filled/wrapped separately by M-q), and even several
*sections* in org/outline-mode would be considered as a paragraph, until
the next blank line, even in the middle of a subsection…

Emacs is very big and so is its manual, but yes I should get more of an
habit of searching within it, instead of simply limiting myself to doing
C-h (maybe both kind of documentations could be hyperlinked? maybe they
already are…)

Like “I want chinese to be written TTB” (well, let’s say japanese and LTR,
given what you say thereafter).

Thank you very much for the encouragement, if I succeed getting again into
hacking I certainly will.
