Oh, then it won't work. The reason this interpolation does not occur is
that we consider % a valid path name. We have been considering how to
solve this, and possibly it requires some config flag to permit
interpolation in mailbox location when given from command line.

A patch is welcome, of course, but please keep this is mind. =)
