Potential asterisk expansion bug in Windows Git Bash?

[Bo Zhang <zhangbodut@gmail.com>]

Hi there,

Not sure if this is the correct channel to submit a bug report for
Windows Git Bash. Please let me know if I did anything wrong.

Today I noticed that on Windows Git Bash, the asterisk (*) is
incorrectly expanded even when it’s in a quote or following a
backslash (\). I’m wondering if this is the correct behaviour (which
seems like to me NOT).

Step to reproduce (in Windows git bash):

zhb@zhb-PC MINGW64 ~/Desktop
$ bash --version

$ cat 1.sh
echo $1

zhb@zhb-PC MINGW64 ~/Desktop
$ bash 1.sh '*'
$A 1.sh 1.txt

zhb@zhb-PC MINGW64 ~/Desktop
$ bash 1.sh "*"
$A 1.sh 1.txt

zhb@zhb-PC MINGW64 ~/Desktop
$ bash 1.sh \*
1.sh 1.txt

Thank you very much.
