revert: do not requires '--all' if '--interative' is present
The '--all' option have been introduced in 890e285c52a1 (August 2006), most
probably to prevent user shooting themselves in the foot. As the record process
will let you, view and select the set of files and change you want to revert, I
feel like the '--all' flag is superfluous in the '--interactive' case.
