This would require moving the first block of HAVE_OPEN_MEMSTREAM stuff
(and it's #else, of course) from below the OPT_HASARG(ops, 'x') test
to above it, so that the result of the tab processing is captured;
and then figuring out how/where to do the corresponding cleanup (maybe
just a "goto" that jumps to the near the end of the function).

Aside, the doc doesn't actually say that -x can't be used with -z/-s/-f
(and print doesn't complain about the attempt) even though that is the
case.
