Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
ARogue family: don't hide messages caused by moving to a new level. new_level() redraws the whole screen, including the message line, so if msg() has just been called, the message will likely not last long enough to be noticed. These cases have been changed so that msg() is called after new_level(). If a fall through a trapdoor is fatal, "You fall into a trap!" is no longer printed, but the tombstone should make things clear.
