What I don't understand is why this change in functionality wasn't
limited to POSIX mode in BASH to preserve compatibility? It's not
that it *can't* be worked around, but with all the changes in the 4.x
series, its as bad as trying to use Unicode sources and data w/Perl
(which has changed, incompatibly, multiple times since 5.6 in
that area as well as others).
That fact that POSIX changed the meaning, to, no longer reflect actual
and historic usage doesn't mean the "Bourne-Again SHell had to follow suit
for it's normal operations.
Interesting how how POSIX, historically, was "descriptive" --
but once people accepted the standard, it's so interesting how they
changed to be prescriptive and proscriptive.
