Historically we've made a few mistakes where they haven't matched the right number. And most non-Googlers are much more familiar with the numbers, so it seems to make sense to rely more on them. Especially in header files, which we actually expect real people to have to read from time to time. Test: treehugger Change-Id: I0d4a97454ee108de1d32f21df285315c5488d886
