Specifically, this CL was generated by the following shell commands: cd system_wrappers for f in $(find . -type f | grep -E '[.](h|cc)$'); do echo >> $f; done git cl format --full Followed by a revert of the changes to asm_defines.h since that file is assembly and not C++, and a manual edit to clock.cc to add some blank lines in the #include list to prevent `git cl format` from sorting <MMSystem.h> before "rtc_base/win32.h". I needed to do this because otherwise `git cl format` introduces a lot of unrelated formatting changes in other CLs that move these files (since `git cl format` will try to re-format all lines of a moved file).
