revert: introduce short option -C for --no-backup Corresponds to -C of the update command. It's much more convenient to use: $ hg revert -aC than having to type $ hg revert -a --no-backup I think the 'no-backup' case is a frequent use case. Introducing short option -C here fits with the muscle memory we have from 'hg update -C', which is described there as "discard uncommitted changes (no backup)".
