  Um, I wasn't just talking about feeding names to the -X option via stdin.  I
was talking about the -X option in general.  BSD 4.3, Ultrix 3.1 and A/UX all
seem to be lacking this option.

  For those of you who are curious about what we're talking about here and
don't have a -X option on their version of tar :-), what it does is reads a
list of regular expressions from the specified file and ignore and files which
match any of those regular expressions.
