You may have this in the queue already, but just in case:
POSIX now specifies that if a standard utility has extended options,

Not quite. POSIX specifies only that -W is reserved for
implementation-defined extensions. glibc's getopt_long _happens_ to
have the implementation-defined extension that '-W foo' is equivalent to
'--foo', so it would make sense that bash support the same extension as
glibc for consistency among GNU programs, but that is _not_ a POSIX
requirement.
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.
Bash currently doesn't use getopt_long for option parsing, but rolls its
own parser. A patch to make the bash parser support mixed long and
short options would also be welcome in my mind.
