Subject: sync with -current:

----------------------------
revision 1.18
date: 2003/06/24 16:23:31;  author: christos;  state: Exp;  lines: +44 -9
Revert previous change, and fix the -T problem differently: When the options
of the second argument are exhausted, call the appropriate getopt() routine
to process the rest of the arguments instead of finishing option processing.
Fixes:
        tar cf - -T foo
