[PATCH] emacs: initialize ido mode in notmuch-mua.el

[Mark Walters]

ido-completing-read is used in notmuch-mua.el without any
initialization.  This should work but a bug (emacs bug #3247) in some
emacs 23 versions (including 23.2.1 from Debian stable) causes emacs
to get stuck in the mini-buffer. This tests to see if ido-mode has
been initialized and if not calls it. This avoids the bug for these
older versions of emacs.

This is the only place that ido-completing-read is used so an alternative 
would be to replace ido-completing-read by completing-read but cworth 
expressed a preference for the ido version in 
id:"87wrhfvk6a.fsf at yoom.home.cworth.org"
