Get a second look at your examples: if the next char has catcode space,
you can use the delimiter spacing; otherwise, you use the
decimal/thousand (whatever appropriate) spacing (which would
again change from region to region).

Nice module! But you still need to insert \tex{digit} before them;
can the thing be implemented, at least in math mode, without the
need for \tex{digit} (only the decimal/thousand separator thing,
not the power thing)?
