Correct Example syntax triggering "block should not end with a whitespace (or comment)"

[hairyhenderson]

Example functions must end with comments, but wsl doesn't like that very much:

Here's a snippet that's failing for me in go-which:

func ExampleWhich() {
        path := Which("sh")
        fmt.Printf("Found sh at: %s", path)

        // Output: Found sh at: /bin/sh
}

$ wsl which_test.go 
which_test.go:124: block should not end with a whitespace (or comment)

I'm thinking wsl should probably ignore this particular check in Example tests.

Another thing to note: I'm using golangci-lint to run wsl, and so I could add // nolint: wsl to ignore these failures. However, that comment then gets put into the godoc:

Thank you for this report! I'll look into this asap!

[hairyhenderson]

@bombsimon I hacked up a fix which I'll PR soon, though it's a bit messy 😉

[hairyhenderson]

See #39 for a potential fix

Looks good! Thank you so much for the report and the PR! Merged and I'll try to include it in an existing PR to update golangci-lint!
