[PATCH 2/9] lib: Perform the same transformation to _notmuch_database_find_directory_id

Subject: [PATCH 2/9] lib: Perform the same transformation to _notmuch_database_find_directory_id

Date: Fri, 18 May 2012 00:13:35 -0400

From: Austin Clements

Now _notmuch_database_find_directory_id takes a flags argument, which
it passes through to _notmuch_directory_create and can indicate if the
directory does not exist.  Again, callers have been updated, but
retain their original behavior.
