convert/svn: refactor svn_source.latest() with a nested function We will call it more than once for reasons detailed later.

convert/svn: clarify svn_source.latest() stop arg default value stop=0 could pass for a valid default value at first sight.

factotum: rename mount and path configuration entries The factotum extension used mount and path entries which were too generic. These have been replaced by mountpoint and executable (respectively) to match existing conventions.

Added signature for changeset d9e2f09d5488

Added tag 2.2-rc for changeset d9e2f09d5488

Makefile: be more careful when cleaning up pure/ components The recent introduction of pure/__init__.py causes mercurial/__init__.py to get clobbered by make clean.

merge default into stable for 2.2 code freeze

commit: add option to amend the working dir parent The --amend flag can be used to amend the parent of the working directory with a new commit that contains the changes in the parent in addition to those currently reported by "hg status", if there are any. The old commit is stored in a backup bundle in ".hg/strip-backup"(see "hg help bundle" and "hg help unbundle" on how to restore it). Message, user and date are taken from the amended commit unless specified. When a message isn't specified on the command line, the editor will open with the message of the amended commit. It is not possible to amend public changesets (see "hg help phases") or changesets that have children. Behind the scenes, first commit the update (if there is one) as a regular child of the current parent. Then create a new commit on the parent's parent with the updated contents. Then change the working copy parent to this new combined changeset. Finally, strip the amended commit and update commit created in the beginning. An alternative (cleaner?) approach of doing this is suggested here: http://selenic.com/pipermail/mercurial-devel/2012-March/038540.html It is currently not possible to amend merge commits or recursively, this can be added at a later time.
