copy: add experimental support for marking committed copies
The simplest way I'm aware of to mark a file as copied/moved after
committing is this:
hg uncommit --keep <src> <dest> # <src> needed for move, but not copy
hg mv --after <src> <dest>
hg amend
This patch teaches `hg copy` a `--at-rev` argument to simplify that
into:
hg copy --after --at-rev . <src> <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.
