Hi Kevin,

thanks for looking into this and sorry for not responding earlier. I would like to understand your use case a bit more - why are you using Cygwin git over [Git for Windows](https://gitforwindows.org/)? I understand that you need to use Cygwin, but why not use the Windows native git binary in Cygwin (instead of Cygwin's version of git)?

Looking at your changes I can immediately see that adding support for the Cygwin version of git will have far-reaching consequences for almost all our code, so I would really like to understand the advantages of using Cygwin git before pursuing this further.

Thanks,
Erik
