Okay, make that `no sane workaround' :-)

More seriously: This fixes the bogosity in the BSD echo, but not the
SysV echo.  Sigh.  (Oh well, at least this makes another argument for
the `4.x > V' side :-) )

Incidentally, /bin/echo works properly with no arguments (produces
a blank line), unlike csh's built-in echo (which requires that empty
argument).
