copy: add experimetal support for unmarking committed copies
The simplest way I'm aware of to unmark a file as copied after
committing is this:
hg uncommit --keep <dest>
hg forget <dest>
hg add <dest>
hg amend
This patch teaches `hg copy --forget` a `-r` argument to simplify that into:
hg copy --forget --at-rev . <dest>
In addition to being simpler, it doesn't touch the working copy, so it
can easily be used even if the destination file has been modified in
the working copy.
I'll teach `hg copy` without `--forget` to work with `--at-rev` next.
