[PATCH] D115061: [clang-format][NFC] Prefer pass by reference

[Marek Kurdej via Phabricator via cfe-commits]

curdeius added a comment.

What do we usually do for output parameters?
I'm ok with both refs and pointers. It seems to me to be google-style thingy to pass by pointer.
It is indeed clearer at the caller site that the passed variable will be modified.
Are you worried about any performance penalty when using pointers? If so, adding `nonnull` attribute or sth like this may help.
