maildirfolder file created in maildir root during auto-creation with 2.3.4.1 but not 2.2.27

[Christian Balzer]

Hello,

it is now nearly 2 years later and we are running 2.3.13 with this bug
still present.
Would be nice if it were acknowledged at least if not even fixed.
And it was confirmed by other people who contacted me directly after
seeing the original report here.

Regards,

Christian
