Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Simplified pitch detection state machine: Considering a pitch to last 1 to 2 seconds only around 5 to 10 iterations are used. As result the used counters had limits of 1 or 2 => not really needed
