annotate mercurial/extensions.py @ 51381:1d488f7be492

crecord: add `content` properties to all nodes In order to have a unified API of what can be searched, let's provide a `content` property to each node type. This way we can search filenames, context headers (e.g. containing function names, if deducible from patch context) or changed lines themselves.
