Fix git cl format when it finds no clang-formattable files.

Currently, if git cl format does not find any clang-formattable files,
either in the path provided on the command line or in the CL as a whole,
then it applies clang-format to all changes in the CL. This CL fixes
this by changing git cl format to not clang-format when it does not find
any changed files that are clang-formattable.

Fix git cl format when the path contains no clang-formattable files.

Currently, if git cl format is run with a particular path, but that path
contains no changed files that are formatted by clang-format, then
clang-format is applied to all changes in the CL. This CL fixes this by
changing git cl format to not clang-format when no changed files are
clang-formattable.
