Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
transactions: convert changes['phases'] to list of ranges Consecutive revisions are often in the same phase, especially public revisions. This means that a dictionary keyed by the revision for the phase transitions is highly redundant. Build a list of (range, (old, new)) entries instead and aggressively merge ranges with the same transition. For the test case in issue5691, this reduces memory use by ~20MB.
