Tab completion behaviour was changed?

[marcvs]

I just updated from 2.2.3 to 2.2.4, which breaks a heavily used makro of mine.

I file this bug, to find out whether this new behaviour is either intentional or an actual bug.

Behaviour until (and including) 2.2.3:
Entering c/home/user/Maildir/<tab><tab> opened the list of folders I could change to. I.e. the list of folders inside Maildir

New behaviour:

• c/home/user/Maildir/<tab><tab> opens the list of folders that macht Maildir` is in (i.e. it looks like I'm one level up)
• `c/home/user/Maildir/pattern fills the list with folders matching pattern

This may be intended, but typical wildcards (*, .) didn't bring back the full list of folders inside my Maildir.
