cmd/go: get -v missing from usage

[JesseWeinstein]

On go version go1.5.1 linux/amd64, the first line of go get --help is: usage: get [-d] [-f] [-fix] [-insecure] [-t] [-u] [build flags] [packages] which doesn't mention the -v flag, even though it does work, and so should be documented. The function of -v appears to be to make the output more verbose.

This was originally reported by @epitron, here #12197 (comment) -- but no-one seems to have made the requested separate bug till now.

CL https://golang.org/cl/27118 mentions this issue.

Nice quick response! I'm not sure I fully agree with documenting the flag both in the list of build flags, and in the detailed list on go get (but not on clean, install, list, run or test) -- but since this bug is now closed, I guess that's another issue, and one I don't feel like opening. :-/

I think documenting the list of build flags in each of the commands that accept them, and referring to go help build for the detailed descriptions, would be better. But, like you said, "docs are hard".

I am thinking about writing a proposal for reorganizing the flags. Current way of mentioning build tags and delegating users to go help build is not working especially for the new comers.
