I don't believe the user ever sees the folder separator.  However, it
would be nice to have a 'typable' character so when you're dealing with
the filesystem hierarchy from a shell, it would be easier to view and
navigate.

I vote for a configuration file option.  I'm not sure how feasible it
would be to change the default at this point since it would break
everyone's existing installations.

The Maildir++ documentation at
http://www.inter7.com/courierimap/README.maildirquota.html shows an
example of a colon being the separator:

"Can folders have subfolders, defined in a recursive fashion? The answer
is no. If you want to have a client with a hierarchy of folders, emulate
it. Pick a hierarchy separator character, say ":". Then, folder foo/bar is
subdirectory .foo:bar."

A tilde might work well also.  The directory on the disk could be called
".Folder1~Folder2~Folder3".

I don't normally create folders with dots in them, but there have been
times in the past when I've tried to and couldn't.
