gofmt -w -s

Many developers have integrated `gofmt`  auto-formatting. S
Some code changes can automatically cause other changes caused through
`gofmt` integration, not related to the intent of the task.

For clarity in future pull-requests, the gofmt issues should be solved
once and for all.

This change doesn't break the code, because it uses official `gofmt` to do
the auto code formatting.
