annotate tools/tb2err @ 12636:e8934ce6ea0f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
util.stanza: Add method for extracting a single attribute value Sometimes you only care about a single attribute, but the child tag itself may be optional, leading to needing `tag and tag.attr.foo` or `stanza:find("tag@foo")`. The `:find()` method is fairly complex, so avoiding it for this kind of simpler use case is a win.
