Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Permit XML entities to be escaped in template output. Useful for creating XML documents directly from Hg logging. Can also be used for HTML. For use in content, will escape '&', '<', and for completeness '>' (although it is not strictly necessary). For use in attributes, will also escape ' and ". Will also replace nonprinting (ASCII) control characters with spaces, since these are illegal in XML.
