Or we could take a simpler approach, and just copy all the metadata
from the original file to the backup.  It's pretty rare that one wants
to back up just some of this stuff, and not the rest.  This would be a
simpler than having individual arguments to copy just this and that,
arguments that I expect in practice are rarely used properly.

Which reminds me, this area is busted for a different reason:
the backup-by-copying-when-mismatch algorithm is done incorrectly on
most modern GNUish or POSIXish hosts, in the sense that copies are
not being made when they should be, and the resulting file metadata
is incorrect (wrong group ID).  I'll file a bug report about that
when I find the time.
