Congratulations on opening your first change. Thank you for your contribution!

Next steps:
Within the next week or so, a maintainer will review your change and provide
feedback. See https://golang.org/doc/contribute.html#review for more info and
tips to get your patch through code review.

Most changes in the Go project go through a few rounds of revision. This can be
surprising to people new to the project. The careful, iterative review process
is our way of helping mentor contributors and ensuring that their contributions
have a lasting impact.

During May-July and Nov-Jan the Go project is in a code freeze, during which
little code gets reviewed or merged. If a reviewer responds with a comment like
R=go1.11, it means that this CL will be reviewed as part of the next development
cycle. See https://golang.org/s/release for more details.

Thanks for the note, I figured as much from the comment in the file header.

I’m not at all familiar about how all that works, so any pointers to docs or other guidance appreciated.

I did try futzing with ./mkall.sh but it made a lot of seemingly unrelated changes, so I wasn’t sure it was the right thing to run.

I’ve now pulled out the relevant changes and push -f’d a git amend
