[PATCH] emacs: Add a space after completed tag operations

Previously, when a user fully completed a tag operation, they had to
press space to begin entering another tag operation.  This is
different from, say, shell file name completion, which typically
inserts a space after an unambiguous completion under the assumption
that the user will want to enter more input.

This patch tweaks `notmuch-read-tag-changes' to act more like shell
file name completion: after an unambiguous tag completion, it now
inserts a space, ready and waiting for another tagging operation from
the user.  This is backwards-compatible with old habits, since there's
no harm in putting an extra space.

Just because of the context, this must be applied on top of the
currently pending tag completion series
id:"1382487721-31776-1-git-send-email-amdragon at mit.edu".  The change
itself should be otherwise independent.
