rebase: fix pull --rev options clashing with --rebase (issue3619) Rebase also have a plain `--rev` option used to select the rebase set (as `--base` or `--source` would). But the content of the --rev option was intended for the remote repo and is irrelevant for the local rebase operation. We expect `hg pull --rebase` to stick with the default behavior here: hg rebase --base . --dest tip(branch(.)) The `rev` option is dropped from the option passed to rebase.

tests: fix broken fix of test-phases output

update: allow update to existing branches with invalid names (issue3710) Starting with 361ab1e2086f, users are no longer able to update a working copy to a branch named with a "bad" character (such as ':'). Prior to v2.4, it was possible to create branch names using "bad" characters, so this breaks backwards compatibility. Mercurial must allow users to update to existing branches with bad names. However, it should continue to prevent the creation of new branches with bad names. A test was added to confirm that 'hg update' works as expected. The test uses a bundled repo that was created with an earlier version of Mercurial.

commit: increase perf by building a new addlist instead of editing the old one When commiting to a repo with lots of files (>170000), manifest.py:addlistdelta takes some time because it's editing a large array many times. Changing it to build a new array instead of editing the old one saves around 0.04 seconds on a 1.64 second commit. A 2.5% gain. The gain here is pretty minor, but it was blatantly at the top of the profiler report and the fix is straight forward. I tested it by comparing the arrays produced by the new and old logic while running all of the tests.
