Hello, If I try something like:

then I get A.c in the output, even if no capital letters are to be found.
The "[a-z]" range expression matches characters between a and z in the
current locale's collation order. The collation order for en_US.UTF-8 and
other locales has uppercase and lowercase alphabetic characters together.
So in those locales your range includes 'a' through 'z' and 'A' through
'Y'. You can change the locale to "C" or "POSIX" to get plain ascii
collation order. You can see the collation order using the sort command.
for c in {32..126}; do eval printf '"%c - %d\n"' $(printf "$'%o'" $c)
$c;done | sort -k 1.1,1.1
for c in {32..126}; do eval printf '"%c - %d\n"' $(printf "$'%o'" $c)
$c;done | LANG=C sort -k 1.1,1.1
The collation order lists 'a' before 'A', but actually lets a later
character break a tie between otherwise equal uppercase and lowercase
characters. Sort will arrange 'a1', 'A1', 'a2', and 'A2' with the '1'
vs. '2' characters acting as a tiebreaker.
...and that it is why instead of using
>> $ ls [a-z]*.c
you should use
>> $ ls [[:lower:]]*.c

Have you applied the tab completion patch that Chet provided here:

Unfortunately doesn't work for me
I'm doing something to Bernd - i.e. I have a function called cd that calls
the builtin cd after doing some extra things. In bash 4.0 with my cd
function enabled I get a bus error and the shell quits each time I attempt a
tab completion on cd. To make things easier I replaced my (rather
complicated) function with the very simple:
function cd
{
builtin cd "$1"
}
I've applied the patch and recompiled but still get the same bus error.
Some info about my build though:
