I got a report of a hang in git's helper functions trying to figure out
how to display results of "git svn info" when run inside ninja, even though
the result is immediately piped to grep. This seems to avoid that.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190808 91177308-0d34-0410-b5e6-96231b3b80d8
This allows the logic to work with Git, and also uses the variable names
to match what Clang is actually looking for.
This changes the interface of GetSVN.cmake. Clang change to follow.
