Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
serve: Don't crash when a post URL doesn't match our expectations. It can happen that a posts source's URL pattern matches that of something else, like a taxonomy page. In this case, don't crash when what we think will be integers turn out to be something else. Instead, just return that no page has been found.
