FWIW, I agree with this, but I think I should review all the unicode
characters in the [:space:] class first. (e.g. ZERO WIDTH SPACE?) If
standards are specific about 'space' being purely U+0020, then
technically we could break some strange programs, but I doubt it.
As this is not a shell-specific problem, I was really wondering if the
scripting languages had encountered it, particularly the 'we support
Unicode' ones... like Perl and Python...
