Not a Go 1 issue, but appeared to be fairly easy to fix.
- Note that a few existing test cases look slightly worse but
those cases were not representative for real code. All real
code looks better now.
- Manual move of the comment in go/scanner/example_test.go
before applying gofmt.
- gofmt -w $GOROOT/src $GOROOT/misc
Fixes#3062.
