I opened up my .gitconfig
and amended it with:
[core] editor = 'C:/Users/miqid/AppData/Local/Code/app-0.1.0/Code.exe'
That did it for me (I'm on Windows 8).
However, I noticed that after I tried an arbitrary git commit
that in my Git Bash console I see the following message:
[9168:0504/160114:INFO:renderer_main.cc(212)] Renderer process started
Unsure of what the ramifications of this might be.
