"Hah", you say?  That's like a triple-dog dare!

Attached is a patch to glob.c to allow case-insensitive globbing when a
program is run from a Windows shell.  It's nothing special -- one extra
#include and a couple tolowers.

I didn't change the set matching so you would still have a little control
over things:

-----------------------------------------
[C:\]ls a*
arcldr.exe    arcsetup.exe

[C:\]ls A*
arcldr.exe    arcsetup.exe

[C:\]ls [a]*
arcldr.exe    arcsetup.exe

[C:\]ls [A]*
ls: [A]*: No such file or directory

[C:\]bash
bash-2.04$ ls a*
arcldr.exe    arcsetup.exe
bash-2.04$ ls A*
ls: A*: No such file or directory
-----------------------------------------

How do I feel about this patch?  Well, I won't be heartbroken if it's
ignored.
