Added all of the MH sources, including RCS files, in

[mmh] / docs / historical / mh-6.8.5 / miscellany / audit / Bug_fixes

Bugs fixed since previous release:

        - @to and @cc are always created. 
        - $apparentlyto is set to $headers{"apparently-to"} if it exists.
        - mail header names that contain hyphens (return-path, replty-to,
          etc.) are parsed correctly.
