And the reason for this is that we always told people "don't use seq"
and they submitted an updated patch. What would we have to do now? We
have to tell them "don't use seq, use test_seq". Therefore, the patch
does not accomplish anything useful, IMO.

The function should really just be named 'seq'.

Or how about this strategy:

seq () {
	unset -f seq
	if ! seq 1 2 >/dev/null 2>&1
	then
		# don't have a working seq; provide it as a function
		seq () {
			insert your definition here
		}
	fi
	seq "$@"
}

but it is not my favorite.
