🚀 go-pugleaf

* changed `|' not to send the message separator strings to the command.
* fixed bug in vm-parse-addresses; no longer considers an empty
  string or a string composed only of whitespace to be an address.
* fixed bug in vm-compatible-folder-p; kill-buffer may make Emacs go
  to an random buffer.
* reorganized the sources, moved everything out of vm.el so vm.el
  can be used as a temp file.  VM compiles to one object file now.
* Prefix arg to `c' (vm-continue-composing-message) now allows
  selection of unmodified Mail mode buffers.
* Fixed the problem with the startup message appearing every time
  you invoked VM instead of just the first time.
* Fixed problem with first message displayed at startup not
  having its headers highlighted properly.
* axed the Full-Name header.
* New variable: vm-mail-header-from
* removed addresses from Cc that are already in To in replies.
* window configurations
  - commands
    vm-apply-window-configuration
    vm-save-window-configuration
    vm-delete-window-configuration
    vm-window-help
  - variables
    vm-window-configuration-file
* used $(EMACS) instead of emacs in the Makefile.
* fixed bug in vm-save-message, needed to restuff deleted messages
  to suppress the delete flag.
* New command: vm-mark-help
* moved the license into the texinfo document, and made the
  license display code use the Info subsystem.
* The Info document goes into the file `vm' now; the README and
  Makefile were changed to reflect this.
* vm-visit-folder depended on insert-default-directory being
  non-nil in order to find folders in the folder directory.  vm
  now temp bind default-directory to folder-directory to make
  sure that relative paths resolve in that directory.
* VM now handles the in-reply-to argument to vm-mail-internal (oops).
* Reply-To instead of Reply-to in outbound mail, a concession to
  broken mailers.
* Fixed vm-grok functions to give up only in the case of MMDF folders.
  A nil value of vm-foldre-type could confuse it otherwise.  This
  is an interim fix.
