Fix some argument parsing stuff in reparse.php
Summary: Currently, "reparse.php --message rXnnn" fails because $reparse_what is an array. Allow multiple named commits.
Test Plan:
$ ./scripts/repository/reparse.php --message rP9030fe8b0904b5291c69a22b0570a10013bba4b2 rP81946fc08d8a737b278255090e296ca92164d672 Running 'PhabricatorRepositoryGitCommitMessageParserWorker'... Running 'PhabricatorRepositoryGitCommitMessageParserWorker'... Done.
