godoc: Doesn't handle repos with no master

[bep]

@kr has created a "left-pad npm like" situation by deleting the master branch in https://github.com/kr/text -- that works in Go 1.6, but not in Go 1.5.4.

I wish that fix had been backported, but you should at least have a look at the logic behind:

https://godoc.org/github.com/kr/text

(I assume godoc.org is backed by you)

It also breaks pre Go 1.6 go get, so I'm not sure if we should encourage that. What's the rationale behind deleting the master branch?

What's the rationale behind deleting the master branch?

Vanity? But it sure gets people to look hard at vendoring.

Please see golang/gddo#405

@kr not sure what point you are trying to make here ...

... but if you can confirm that you have no intention to reintroduce the master branch, I will have to fork your repo and try to patch up my stuff.

It seems reasonable that tools should use the default branch even if it's not master. Since the go tool already does and there's a separate gddo issue, I think there's nothing to be done here and this issue should be closed.
