Summary: isn't keeping original "\nFrom " line easier than reconstructing it?

I too was disappointed to find it wasn't easy to get from the mh
message format back to the unix maildrop format.  Instead of writing
a script to reconstruct the delimiting line I changed mh so that it
doesn't throw that line away.  This change affects nine lines in two
files, and is currently part of the RPATHS option.
Bugs:  (1) annotations get prepended to the message, so you cannot
depend on the saved delimiter being the first line of the message.
(2) this probably should be separated from the RPATHS option.
(3) the name of the new component might conflict with officially
recognized component names.  (4) there is no guarantee or warranty
of any kind associated with these changes.
