revert: drop requirement to use -r to revert with two parents This reduces documentation confusion between the need to: a) hg revert -a -r . (drop all changes from a merge) b) hg up -C . (drop the second parent entirely) Currently revert is one of two commands (the other being tag) that still complains about uncommitted merges, dating from its former use of a generic defaultrev function that aborted.
