Most notably, -watch now supports a Maildir with multiple lists.
(works better with the "watcheader" directive).

It should probably resolve symlinks in the future, too;
since I seem to recall some weirdness in that + Filesys::Notify::Simple

Eric Wong (3):
  watchmaildir: support multiple inboxes in the same Maildir
  watchmaildir: get rid of unused spamdir field
  watchmaildir: normalize Maildir pathnames consistently
