Re: [PATCH] Add clang-format config to contrib folder

[Sebastian Pop <sebpop at gmail dot com>]

Martin, thanks for getting this patch out.  I like the patch.
Jeff, clang-format has scripts that allow formatting only the lines
touched by a patch.
It also has a script to integrate with git:
https://llvm.org/svn/llvm-project/cfe/trunk/tools/clang-format/git-clang-format
We could use those scripts in a commit hook to automatically enforce
correct formatting of new patches.
