mbsync expects messages moving inside a Maildir (from new to cur, for example) to mantain its basename.
This change tries to fix issue #321. It might be more sensible than the change proposed there. I can't see this negatively affecting other users, as it is my impression that the whole mu4e-change-filenames-when-moving was introduced to satisfy mbsync.
What do you think?
* mu-proc: Don't rename when moving inside a Maildir
`mbsync' expects messages moving inside a Maildir (from `new' to `cur',
for example) to mantain its basename.
Okay, let's give it a try... thanks.
