[PATCH 5/6] emacs: simplify `notmuch-show-get-messages-ids{, -search}'

[Pieter Praet <pieter@praet.org>]

* emacs/notmuch-show.el

  (notmuch-show-get-messages-ids):
    If provided with optional arg SEPARATOR, return a string consisting
    of all Message-Id's, separated by SEPARATOR.  Also improve original
    docstring wrt default return value.

  (notmuch-show-get-messages-ids-search):
    Removed, as its functionality is now in `notmuch-show-get-messages-ids'.

  (notmuch-show-tag-all):
    Call `notmuch-show-get-messages-ids' with SEPARATOR arg instead of
    `notmuch-show-get-messages-ids-search'.
