* mh-e: Created directory. ChangeLog will appear in a week when we
release version 7.2. * lisp/mail/mh-alias.el, lisp/mail/mh-comp.el, lisp/mail/mh-customize.el, lisp/mail/mh-e.el, lisp/mail/mh-funcs.el, lisp/mail/mh-identity.el, lisp/mail/mh-index.el, lisp/mail/mh-loaddefs.el, lisp/mail/mh-mime.el, lisp/mail/mh-pick.el, lisp/mail/mh-seq.el, lisp/mail/mh-speed.el, lisp/mail/mh-utils.el, lisp/mail/mh-xemacs-compat.el: Moved to mh-e. Note that reply2.pbm and reply2.xpm, which were created by the MH-E package, were left in mail since they can probably be used by other mail packages. * makefile.w32-in (WINS): Added mh-e. * makefile.nt (WINS): Added mh-e.
