But the X11 intensity string specification doesn't accept whitespace or
hexidecimal values, so it's different from the rgbi specification that
was implemented in Emacs.  Though in practice, tolerance for whitespace
is X server-specific.  For the same reason, we don't use XParseColor to
parse color specifications.

If the happenstance doesn't cause trouble, there is no need to get rid
of it.

Thanks.
