    You're right; this problem does not occur with non-MIME messages
under 24.2 (my current test system).

    I think your patch may not work correctly if the user adds a "From "
line to a MIME message.  Seems like there are two choices: (1) give an
error in that case and refuse to exit editing (similar to the screwed up
headers case) or (2) unescape From lines when the edit starts and
re-escape them when the edit finishes.  (2) seems friendlier to users as
it means users don't have to manually escape From lines when editing.
