You may have this in the queue already, but just in case:
POSIX now specifies that if a standard utility has extended options, then you accomplish it with ``-W option-name[=opt-arg]''. I wouldn't care, but I wanted to add ``--noprofile --norc'' to the command line and, for debugging purposes, I aliased "bash" to "bash -x". Oops. Two issues: 1. I'd be nice to be able to interleave short and long options, and 2. "bash -x -W noprofile -W norc" should also work. Thank you so much! Regards, Bruce
