comparison hgext/children.py @ 4783:be78ab217109

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
children extension: Don't abort when looking at the null revision. Since 62c56d8f368b revlog.children only returns real children, so this is no longer a problem.
