* lisp/minibuffer.el (completion--done): New fun.

* lisp/pcomplete.el (pcomplete-completions-at-point):
* lisp/comint.el (comint--complete-file-name-data): Use :exit-function
instead of completion-table-with-terminator so it also works for
choose-completion.
(shell-filter-ctrl-a-ctrl-b): Work as a preoutput filter.
(shell-mode): Put shell-filter-ctrl-a-ctrl-b on
comint-preoutput-filter-functions rather than on

Bump custom version.
The initial regexp-opt was bracketed by \\( \\)?, so it might as well
have not been there at all. This change makes it non-optional, and
adds back "^". Hopefully the behaviour is now closer to that of emacs-23,
before it was re-written in http://debbugs.gnu.org/2817.
* comint.el (comint-history-isearch-search): Instead of
`comint-line-beginning-position', use `comint-after-pmark-p'
to check if point if before the process mark, and go to
`process-mark' in this case.
