You can change target for Git Bash shortcut from:
"C:\Program Files\Git\git-bash.exe" --cd-to-home
to
"C:\Program Files\Git\git-cmd.exe" --no-cd --command=usr/bin/bash.exe -l -i
This is the way ConEmu used to start git bash (version 16). Recent version starts it normally and it's how I got there...
