revset: stop lowercasing the regex pattern for 'author' It was probably unintentional for regex, as the meaning of some sequences like \S and \s is actually inverted by changing the case. For backward compatibility however, the matching is forced to case insensitive.

repair: clean up stale lock file from store backup Since we did a directory rename on the stores, the source repository's lock path now references the dest repository's lock path and the dest repository's lock path now references a non-existent filename. So releasing the lock on the source will unlock the dest and releasing the lock on the dest will no-op because it fails due to file not found. So we clean up the dest's lock manually.
