Revert Erik's changes... they were broken since there weren't enough

bits for the extra ISblank flag.  Instead, hardwire isblank() to not
depend on locale for now.  At least it will work for space and tab
in the immenent release.  This will all be blown away for the next
release anyway, as I should be committing my new stuff in the next
day or two.
