Subject: 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.
