changeset 22393:293930a1fa0a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
templater: implement __len__ for _hybrid Objects of class _hybrid are returned by such template keywords as children, bookmarks, tags and others, and also by revset() template function. They are representing "list of strings" (as hg help template says) for use in templates. So it would be logical to implement a handy way to count the number of strings in such list, and that's what __len__ method does.
