Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
setup: use changessincelatesttag from archive if present changessincelatesttag gives one a better idea of how much the code has changed since. Since changessincelatesttag is always greater than or equal to the latesttagdistance (see previous patch for why), this will always produce version numbers greater than or equal to the previous scheme.
