I think when you need to do more advanced things, you should use
a file system that can support you needs.  I find the 8.3 convention
very limiting and have not bothered with the extra burden to
support it in some of my work (in MHonArc, the docs require long

Even Windows95 supports long filenames (in a bastardized way).

AFAICS, mhonarc.db is wiped when the archives are rebuilt ... and all 
that would be needed is to ensure that filename.db is not wiped on a 
rebuild, and its data reused.   That way, we could retain the current 
flexibility of filename format (which has other advantages, such as 
being reasonably transparent) and add permanency.

   This sounds more flexible.  I worry about the removal of filename.db,
   but I guess I could just be more careful.  :)

   The .db file will need to search in both directions -- it needs to
   check and see if a filename has already been used and see if a 
   filename exists for a Message-Id:/md5sum pair.

   Of course, I have no idea how hard it would be to implement this.
   Guess it's time to start poking around the source again (or be
   *really* nice to Earl :)

The main problem is the lack of abstraction of message filenames
in the current code base.

As for 8.3 support, I will not bother with it.  If someone really
needs it, they will have to contribute it.
