I'm not able to reproduce this.

go get drops down into git to fetch something. It can do one of two things...

• For new clones it runs git clone {repo} {dir}
• Downloading updates it runs git pull --ff-only

If you've altered either of these commands on your own it can cause go get to behave in unintended ways. Have you made any custom changes to git that could cause this?

I just upgraded git to latest via brew.
made no difference.

its so weird because the code is such standard golang package structure.
