     bar
 
 foo was clean:
   $ hg st -AC foo
   C foo
 Trying to copy on top of an existing file fails,
   $ hg copy -A bar foo
   foo: not overwriting - file already committed
   (hg copy --after --force to replace the file by recording a copy)
 same error without the --after, so the user doesn't have to go through
 two hints:
   $ hg copy bar foo
   foo: not overwriting - file already committed
   (hg copy --force to replace the file by recording a copy)
 but it's considered modified after a copy --after --force
   $ hg copy -Af bar foo
   $ hg st -AC foo
   M foo
     bar
 The hint for a file that exists but is not in file history doesn't
 mention --force:
   $ touch xyzzy
   $ hg cp bar xyzzy
   xyzzy: not overwriting - file exists
   (hg copy --after to record the copy)
