Subject: [PATCH] zshrc: Don't use is-at-least anymore

While this can be a useful function, it really is a little overkill
for out purposes; especially, since we provide much simpler fallback
functions, when it is not available.

added is43() as well, which is currently not used, but probably should. :-)
