Added signature for changeset b96cb15ec9e0

Added tag 2.9.1 for changeset b96cb15ec9e0

merge: audit the right destination file when merging with dir rename

setup: specify --prefix="" for install-home-bin to avoid badness with defaults Sometimes (I'm not sure when) setup.py gets a default value for --prefix, which breaks --home. This fixes that for me.

revset: add 'only' revset Adds a only() revset that has two forms: only(<set>) is equivalent to "::<set> - ::(heads() - heads(<set>::))" only(<include>,<exclude>) is equivalent to "::<include> - ::<exclude>" On a large repo, this implementation can process/traverse 50,000 revs in 0.7 seconds, versus 4.2 seconds using "::<include> - ::<exclude>". This is useful for performing histedits on your branch: hg histedit -r 'first(only(.))' Or lifting branch foo off of branch bar: hg rebase -d @ -s 'only(foo, bar)' Or a variety of other uses.

revset: added basic operators to orderedlazyset Now __and__ and __sub__ return orderedlazyset.

revset: changed revset code to use filter method Revset methods now use the filter code to apply a condition.
