changeset 24292:b7add2ebef9e

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
manifest: rewrite find(node, f) in terms of read(node) Since find() now always works with a full manifest, we can simplify by calling read() to give us that manifest. That way, we also populate the manifest cache. However, now that we no longer parse the manifest text into a Python type (thanks, lazymanifest/Augie), the cost of parsing (scanning for newlines, really) is small enough that it seems generally drowned by revlog reading.
