REVISION SUMMARY
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 `-r` argument to simplify that into:
hg copy --after -r . <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.

-check that stat information such as mtime is preserved on rename - it's unclear
-whether the `touch` and `stat` commands are portable, so we mimic them using
-python. Not all platforms support precision of even one-second granularity, so
-we allow a rather generous fudge factor here; 1234567890 is 2009, and the
-primary thing we care about is that it's not the machine's current time;
-hopefully it's really unlikely for a machine to have such a broken clock that
-this test fails. :)

- $ mkdir mtime
-Create the file (as empty), then update its mtime and atime to be 1234567890.

-(modulo some fudge factor due to not every system supporting 1s-level
-precision).
