Re: [PATCH] On Windows, avoid git-gui to call Cygwin's nice utility

>It's a common case for Windows developers to have both Cygwin and msysGit

>So we only call nice.exe on Windows if it is in the same directory as git.exe.
>This way, this work-around does neither affect a pure Cygwin environment, or
