In that v3 patch, I've added iswblank() in the list of functions
to check before enabling "unicode support". Maybe we should do
like for isblank() so that we can still have unicode support if
iswalpha()... are present but not iswblank() (and have
iswblank() check for spc and tab only then).

OK, I'll send a v4 patch tonight.
