Log:
[clang-format] Allow git-clang-format to handle empty extensions.

Most of libc++'s header files don't use extension. This prevents
using git-clang-format on them, which is frustrating.

This patch allows empty extensions to be passed using either
the --extensions option, or the clangformat.extensions git-config
value.
