Do you have any specific suggestions what should be in the message? The libc++ "I implement something" patches are most of the time quite straight-forward, since you can look at the standard and know what's going on. It's also the best source, since it's the authoritative document here, and is also what anybody who cares to actually look at the patch should check against for correctness.
