using readrune() and iswspace().
musl for instance doesn't differentiate between iswspace() and
isspace(), but when it does, the code will be ready.
It goes without saying that GNU coreutils don't use iswspace()[0].

Use size_t for all counts, fix the manpage and refactor the code.
Here's yet another place where GNU coreutils fail:
sbase:
$ echo "GNU/Turd sucks" | wc -cm
15
coreutils:
$ echo "GNU/Turd sucks" | wc -cm
15 15
Take a bloody guess which behaviour is correct[0].

It actually makes the binaries smaller, the code easier to read
(gems like "val == true", "val == false" are gone) and actually
predictable in the sense of that we actually know what we're
working with (one bitwise operator was quite adventurous and
should now be fixed).
This is also more consistent with the other suckless projects
around which don't use boolean types.
