:That means an and more and possible double evalution of the
:argument. Actually, it is allowed by SUS to have a control character
:as printable. Question is, are there non-tab non-space white spaces, which are
:control chars and not graphs?

    The only thing I can think of is shift-space (0xa0), but isblank()
    returns FALSE for that (I think properly).

    Either way is fine with me.  Just choose one and do it so we can 
    move on to other issues.
