Comment 1:

this is "introduced" by: https://golang.org/cl/6610051

Comment 2:

I suspect this is coming from different people running different (and not up-to-date)
versions of gofmt.
As pointed out by minux.ma, the CL 6610051 - which fixed a real bug - caused some fields
to be aligned differently than before. In fact, the alignment before - while it may look
better in some places - was not symmetric (depending on which way the field width
changed - up or down on the page)  alignment would change or not.
The way out is probably to enforce that the latest version of gofmt is used before
submits.

Status changed to WorkingAsIntended.

Comment 3:

That particular case is perhaps a bad example then? It does look like the old style was
better.
