maildir on !bash is fubar
Yeah, I was checking custom backups I made for a client and it kept writing over the daily.1 directory. I traced down the code to realize that there is some weird bashism that was crashing on dash (prolly since that time where bash got 0wned), that made backup just "write over the old one".

I hacked the patch by hand on concerned servers, but it is nice to check that we aren't all not having as much backups as we thought we would.
