Use diff_free_queue() instead of open-coding it. This shortens the code and make it less repetitive. Note that the second hunk in diff_flush() is interesting, because the 'free_queue' label separates the loop freeing the queue's filepairs from free()-ing the queue's internal array. This is somewhat suspicious, but it was not an issue before: there is only one place from where we jump to this label with a goto, and that is protected by an 'if (!q->nr && ...)' condition, i.e. we only skipped the loop freeing the filepairs when there were no filepairs in the queue to begin with.
