uncommit: expose the feature with a '--extract' to amend The name of the "uncommit" feature have been an ongoing issue, but no better name have been found in the past year. We try another approach by exposing the 'uncommit' feature directly in `hg amend`. The command will not be able to do both operation a the same time (add new change to the commit + extract should change, but this is already the case with the two command today.
