gitk: Fix bug causing nearby tags/heads to sometimes not be displayed
When we compute descendent heads and descendent/ancestor tags, we cache the results. We need to be careful to invalidate the cache when we add stuff to the graph. Also make sure that when we cache descendent heads for a node we only cache the heads that are actually descendents of that node. Signed-off-by: Paul Mackerras <paulus@samba.org>
