readme: update the contribution process The inability to easily pull from pull request on bitbucket and the lack of obsolescence support there are too much pain. Patchbombed contribution are flowing so we drop the bitbucket mention in the README.

merge 5.x line into stable (drop pre hg-3.2 compat)

evolve: add the missing newline to output messages where needed

evolve: add the missing argument to a debug statement

uncommit: abort when rev specifies the current changeset The uncommit command now fails when the rev argument indicates the current changeset. Previously this aborted in the changeset obsolescence machinery when the current commit tries to obsolete itself. Using the rev argument like this indicates a misunderstanding, so printing an uncommit-specific error should make it easier to understand what went wrong.

test-amend: add a test for amend with no configured username (issue4211)

evolve: preserve branch change evolve will now preserve branch change. If the evolved changeset had a different phases than its parent, this branch name will be preserved. This allow propagation of branch change during amend but do not overwrite special branch name on children,

amend: allow the --logfile argument to work properly Though documented to work, using --logfile previously set the message option to that of the parent commit, and cause amend to abort with this message: abort: options --message and --logfile are mutually exclusive It's not clear why the 'edit' option is popped, but this option is only fetched in order to let the core commit command do the work.

Added tag 5.0.0 for changeset c13b408c0006

setup.py: bump version to 5.0.0
