Thanks for the suggestions, always very welcome. Yes, MD is a right
place, even if BTS bugs.mutt.org would have been yet righter. A Bug
Tracker has the tremendous advantage to not let us forget something we
don't do immediatly.

The <F1> is right. But simplified: Doesn't explain the details of
the used statistical heuristic. See sendlib.c:update_content_info() and
mutt_make_file_attach(), or grep for "(hi|lo)bin".

That's quite strange for a tbz2, but admitedly can happen for
specific files, containing a low ratio of bytes below 32, like texts.

Yes, agreed. Modeled after gzip entries, and unless someone knows
more official types, what about adding to sample mime.types:
| application/x-bunzip2 bz2
| application/x-tar-bz2 tbz2 tar.bz2

Warning: Touching a carefully crafted heuristic could do harm. It's
a delicately equilibrated compromise. Could you please make the tbz2
available to us somewhere?
Bye! Alain.
