gofmt 1.11 fails for files that pass on 1.10

[krasi-georgiev]

What version of Go are you using (go version)?

1.10
1.11

our Travis CI runs the same tests agains 1.10 and 1.11 and since the last few days all test fail for some additional white space changes.

https://travis-ci.org/prometheus/prometheus/builds/399060443

If you notice the same passes under 1.10

the command that runs is
! gofmt -d $(find . -path ./vendor -prune -o -name '*.go' -print) | grep '^'

I believe this is unfortunate. Looks similar to #25161.

@griesemer can confirm but I believe he is in vacation.

yep that looks like it. closing now and will look for a solution in the CI pipeline.
