Maybe your background is different from mine---you work on a single
program, I tend to think more about the full system.

Fixing gnulib ensures that, on non-GNU systems, everyone will get the
same result from gnulib users (BTW, note that grep's fix for the problem
did not introduce a particular policy: instead, it just relied on
gnulib's fix).  It's the best you can do on non-GNU systems.

But that's not enough on GNU systems, because GNU systems will always
have regex in glibc and many programs will use the regex that is in
glibc.  On such a system, modifying glibc is the only way to ensure that
everyone will get the same result, either a<A<b or a<b<A.
