annotate bin/sat @ 3118:02492db1ce39

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
quick frontend (app): call `getReady` once connected to bridge: namespaces and encryption plugins are only retrieved once backend is ready, else they may not yet be available (can happen notably when the backend is start at the same time as the frontend, e.g. on Android).
