Subject: (shell-pcomplete, shell-pcomplete-reverse): New functions.
X-Git-Tag: ttn-vms-21-2-B4~16510
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=d9c62d8f6cbb433f2db6bba97d5b56cf5e6a1d1f;p=emacs.git

(shell-pcomplete, shell-pcomplete-reverse): New functions.
(toplevel): Bind them.
(shell-mode): Don't set `comint-dynamic-complete-functions'; it is
not necessary now that we use pcomplete.
