You can do that, no problem. Have is_inside_wc_ng() raise that
specific error, rather than returning a version number. It knows the
root of the wc-ng tree.

And since it is raising an error, it doesn't even have to get into the
format number game. It has two options: raise an error, or return 0
for "not a wc". Simpler, *and* you get what you want.
