[PATCH] D86993: Document Clang's expectations of the C standard library.

[Ralf via Phabricator via cfe-commits]

RalfJung added a comment.

It would probably be worth including all string functions that take a length in such a DR. In Rust we are currently puzzling over whether calling 0-length `memcmp` on something like `(char*)42` is okay or not. If not we'd have to introduce a pretty pointless branch.
