comparison parser.js @ 68:3a169ebb3224

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Change strategy for handling true and false to avoid some initialization order problems and improve performance. Add support for negative integer literals. Update samples to reflect true/false change.
