[llvm-dev] 'git llvm push' not working for me on Windows

[via llvm-dev]

I am consistently getting:

`git apply -p2 -` returned 1
error: include/llvm/IR/DIBuilder.h: No such file or directory
[[ etc ]]
Patch doesn't apply; maybe you should try `git pull -r` first?

My usual response to a problem from git-llvm (which is most often
an anti-virus issue) is to blow away .git\llvm-upstream-svn but
that doesn't help this time.

I see James Knight did a "performance improvement" on Friday,
perhaps that doesn't work so well on Windows?  The main
performance cost is one-time, and as long as my anti-virus isn't
trashing things behind my back the performance is just fine;
so it's not clear this is really a necessary improvement.
If it's interfering with developing the new git repo, then I'd
suggest making it optional or platform-dependent.

As a workaround I fetched the previous version of git-llvm 
and put it earlier in my PATH, that worked.
