Thanks for merging the uncontroversial patches. Fixing the flagged
problems is not obvious to me, it really depends on your intentions.

For the first FIXME, the documentation for notmuch_directory_delete
says (lib/notmuch.h:1971):

 * Delete directory document from the database, and destroy the
 * notmuch_directory_t object.

but that is not what happens, for example, if the call to
_notmuch_database_ensure_writable fails. Then the notmuch_directory_t
object is only destroyed by the caller (see the end of
_remove_directory function, notmuch-new.c:886).

The comment should clearly say if the object is always destroyed or
only if no error happened.

For the second FIXME, I don't quite see why not just use the bsearch
function. It could be called either with strcmp (if exact is true) or
with a simple wrapper around strncmp (if exact is false). This wrapper
could replace the string_cmp routine, so together with bsearch this
could even make the code smaller.

Also, I don't really understand the intention behind declaring
string_cmp as returning notmuch_bool_t and then, in bsearch_first,
casting its result to int.

Am I missing something?
