[Toybox] awk seen in the wild

That assumption doesn't make sense unless you only work on your own code.

Look at something like Aboriginal Linux -- even if toybox were
complete, it would still be mostly other people's code (LLVM,
binutils, and whatnot).  Pretty much EVERY package uses a bunch of
shell and make, lots of it probably autoconf generated, and awk is
pretty common as well.  Those languages add up to about 150% of
functionality as far as I can tell, not 300%.

Rob apparently has no desire to learn awk, bc, m4 and all the rest
(and I don't blame him).  But he's learning those languages precisely
because he's dealing with other people's code.
