-This script reads input from a unified diff, runs clang-tidy on all changed
-files and outputs clang-tidy warnings in changed lines only. This is useful to
-detect clang-tidy regressions in the lines touched by a specific patch.
-Example usage for git/svn users:
-
-  git diff -U0 HEAD^ | clang-tidy-diff.py -p1
