Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add LTR inversion code to diagram generator. This code is used in serveral diagrams and as it modifies a whole diagram it should be central. (This should also make maintenance easier). This function can be called by processors to make sure that their data is plotted with an LTR waterflow.
