Vim hangs when opening from gitu on Windows

[McPhale]

When opening vim from gitu (when committing, for instance) on windows, the editor does not respond to keystrokes. The graphical version of vim seems to work just fine. Not sure if this is a gitu issue or not, but vim works fine in other scenarios. I've tried setting the editor variable in both git config and the system environment variables to see if that makes a difference, and have tried removing my vimrc to see if there was a problem there, but it didn't change the behavior. The issue also appears in both cmd and windows terminal running powershell core. The editor variable is set to "C:/Tools/Vim/vim91/vim.exe".

Any thoughts?

Thanks for the very cool utility!
