Shouldn't we still support the option, even if it is a no-op in the
common case, so that someone can do actions similar to:
alias mysum='cksum --untagged '
and then invoke 'mysum --tag' to turn it back on?
Maybe.
Perhaps on some systems only cksum might be installed,
with md5sum etc. being provided as simple wrappers like:
exec cksum -a md5 --untagged "$@"
Though that begs the question, should cksum support all of
--tag, --text, --binary ?
I'd be 60:40 for adding the --tag option to cksum,
