That would still call libc, and still depend on LC_CTYPE. Should we use
pure ASCII variants?

There was also some discussion about forcing LC_COLLATE and LC_CTYPE to
C, now that the default collation doesn't depend on them any more (cf.
option 1):

If we do that, then it would be fine to use isdigit/isspace.
