Right you are, and thanks for reporting it.  I fixed it in
bzr 105261 on the trunk.  copy-file's help string says "try to
transfer the uid and gid", with the implication that it's OK
if the attempt fails and no diagnosis should be made.

The doc uses stronger language for file modes ("This function always
sets the file modes") so a diagnostic is more appropriate there
and I left that one alone.
