D8030: uncopy: add support for unmarking committed copies

[pulkit (Pulkit Goyal)]

pulkit added a comment.


  I don't feel very good with this because this makes `hg uncopy` a history editing command. Something like `hg uncopy --after` which makes the changes in wdir which can be committed afterwards sounds best, but I am not sure if that's possible.
