[BUG] The git in msys act different from git-for-windows's released git

[lygstate]

Describe the bug

It's in the bash shell, and open a cmd
using /usr/bin/git,
the source code of test.c are

#include <stdio.h>

int _CRT_glob = 0;

int main(int argc, char** argv) {
    int i;
    for (i = 0; i < argc; i+= 1) {
        printf("%s\n", argv[i]);
    }
}

Whe I compiling test.exe with msys2 gcc, not msys2/mingw gcc, the running result are:

C:\work\xemu\qemu>test describe --match v* --dirty --alway
test
describe
--match
version.rc
version.texi.in
--dirty
--alway

C:\work\xemu\qemu>
C:\work\xemu\qemu>test describe --match "v*" --dirty --alway
test
describe
--match
v*
--dirty
--alway

C:\work\xemu\qemu>
C:\work\xemu\qemu>test describe --match 'v*' --dirty --alway
test
describe
--match
v*
--dirty
--alway

C:\work\xemu\qemu>

So it's seems the real cause are comes from msys2 gcc compiled program that doesn't recognize _CRT_glob and respect Windows wildcard sematic and that's seems not necessary, because that's bash's job, on posix platform there is no such
feature at all

According to magit/magit#2246, So th solution are using
CYGWIN=noglob and MSYS=noglob in the environment variable
