Description:

This is the way to reproduce the error:

$ git-clang-format
File "/usr/bin/git-clang-format", line 130
print 'Ignoring changes in the following files (wrong extension):'
^
SyntaxError: invalid syntax
$

git-clang-format belongs to clang package.

$ pacman -Qi clang
Name : clang
Version : 3.6.0-3

git-clang-format is a Python script and it requires Python v2. If the first line of script is changed to "#!/usr/bin/env python2", instead of "#!/usr/bin/env python", git-clang-format works fine.
