Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
pull: save the last pulled revision *after* converting revisions Otherwise, a KeyboardInterrupt may lead to an unpulled revision being incorrectly saved as pulled in the lastpulled file. This will lead to the interrupted revision being incorrectly skipped at the next pull, leading to an incorrect conversion -- one might even say corrupt. Due to it's nature of requiring a manual interrupt, this bug is difficult to test.
