Git "supports" MinGW, or at least wants to. And yes, you can put bash in 
there, but we'd be *so* much better off if we had no shell scripting at 
all.

Another thing I find annoying (even as a UNIX user) is that whenever I do 
any tracing for performance data, shell is absolutely horrid. It's *so* 
much nicer to do 'strace' on built-in programs that it's not even funny.

It's also sad how many performance issues we've had with shell, just 
because even something really simple (like a few hundred refs) is just too 
slow for shell scripting.

Yeah, and that's probably my pet peeve. I'd love to see a built-in "git 
commit" and "git fetch". The "fetch--tool" thing in next gets rid of some 
of the latter (and apparently the worst performance problems), but it's 
sad how we have a really nice builtin "push", but our "fetch" is still 
mostly really hairy shell-code (not just "git-fetch.sh" itself, but 
"git-parse-remote.sh".

A gold star for whoever gets rid of any of of commit/clone/fetch or 
ls-remote

(ls-remote isn't that big or hairy, but I mention it because it's a user 
of "parse-remote", so making even just ls-remote built-in is probably 
going to help with fetch/clone eventually).
