nolintlint: too many whitespaces removed after autofix

[ldez]

Related to #1573

The fix removes all whitespaces, the choice to remove all the whitespaces, in this case, seems not right.

---

before the fix:

// wantedErrors parses expected errors from comments in a file.
// nolint:nakedret
func wantedErrors(file, short string) (errs []wantedError) {

after the fix:

// wantedErrors parses expected errors from comments in a file.
// nolint:nakedret
func wantedErrors(file, short string) (errs []wantedError) {

OK

before the fix:

// wantedErrors parses expected errors from comments in a file.
//    nolint:nakedret
func wantedErrors(file, short string) (errs []wantedError) {

after the fix:

// wantedErrors parses expected errors from comments in a file.
//nolint:nakedret
func wantedErrors(file, short string) (errs []wantedError) {

KO

I'm not completely sure it is possible to determine the user's intent in this case. We don't know whether the expected coding style is to use machine-readable directives or not (unless allow-leading-whitespace is explicitly disabled in the config for nolintlint). One option might be to have nolintlint simply not try to fix this case unless allow-leading-whitespace is disabled and simply defer to the user on how to fix it. Does that sound reasonable?

I think that something like that can be possible:

allow-leading-whitespace:

• true: just keep only one whitespace
• false: drop the whitespaces
