git gui

be sure to read git on windows to get a nice working git gui from cygwin on windows

1. run this to tell git you want to ignore these warnings

   git config --global gui.gcwarning false

2. the warning is actually an indication that you might want to cleanup your repo, so if you keep the warning you may want to run this when you see it

   git gc --prune=now
