I get that Google always really really wants a CLA since it does things the BSD license doesn't (patent grant!). I also agree that, practically speaking, legal stuff is absolutely part of the process of getting the asm crypto stuff merged in. And I know you're qualified. But I read the initial comment as saying, specifically, no third-party copyright notices, ever. I have code up with under Go's license with more than one set of copyright notices (https://github.com/twotwotwo/sorts https://github.com/twotwotwo/sorts). From a grep, Go 1.4 has ~1,026 non-"The Go Authors" copyright notices in ~271 files in ~35 dirs (Lucent and other Plan 9 copyright holders, Sun, individuals, MPEG and yacc authors). If there is stuff I should read/learn to have any hope of understanding what's OK (to keep my own stuff clean, and generally), it would help me to know.
