Oops, I tried to mimic what is done for 'anchors', and I failed to
notice that apparently the elements of the options->anchors array are
only free()'d when --patience is also used and the array pointer itself
is never free()'d at all. Given this, I believe I need to fix
diff_opt_ignore_regex() in patch 2 and also make sure that the memory
allocated in diff_opt_anchored() gets properly released - in another
preliminary clean-up patch?
At first glance, diff_flush() - specifically the part below the
'free_queue' label - looks like a sane place to free() things. Am I
mistaken?
