AFAIR, we don't even exclude files with a colon.

About my patch, I decided to ignore dot files only to both go the lazy
way and be legacy compatible as much as possible.

However, I'd welcome patches for stricter matching rules about naming
schemes as long as it's made optional. We could even make such option
the default and see if counter examples exist in wild since users can
roll back to the historic behaviour. :-)

Something like "maildir_scan_strict_naming = yes" and a documentation
line requesting feedback from users having to change to "no".
