This breaks the Vim integration for me:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/work/llvm/tools/clang/tools/clang-format/clang-format.py",
line 30, in <module>
    binary = vim.eval('g:clang_format_path')
vim.error: Vim:E121: Undefined variable: g:clang_format_path


(I've worked around this locally by setting g:clang_format_path, but
it might break others too.)
