TBF, Git operations on repos with many small files are extraordinarily slow on Windows (probably not Git's fault, because all file operations involving many small files are slow on Windows, even copying stuff around on the desktop), so that feature is much more critical to have on Windows than Linux.
Today I learned that “cross-platform” means “all-platform.”
Considering there is only really three platforms I think it's a pretty fair assumption.. and we're talking about git here, you can assume cross platform includes Linux.
It looks cross-platform enough to me.
After all these years of Windows-only or MacOS-only software, you guys deserve this.
