annotate mercurial/bitmanipulation.h @ 38228:8bded7eae26c

templater: consistently join() string-like object per character (BC) The old behavior was copied from join() of a lazy generator string, which was unified to the behavior of join() of a byte string by the previous patch. This patch fixes the mappable type to do the same.
