Git Bash Completion Not Working In Emacs

[Marko Vasic <vasic@xxxxxxxxxx>]

Hello,

Git bash completion script works perfectly under the terminal,
however, it does not work in Emacs (neither shell nor gui mode). Did
anyone encounter this issues and how can it be solved?

System I use:
OS: Ubuntu 17.10
Emacs: 25.2.2

Thanks,
Marko
