Add support for applying rules only in particular range of a specific file.

Include/Exclude specific (patterns) of files

[dvmarcilio]

As context, specifying a particular range in a file for a rule could be helpful when there are duplicated nodes.
More specifically, a seemingly common pattern in Go is to keep assigning an error to the same identifier.

Currently, there is no easy way to clean up the error handling if statement for the call with enabledFlag in the snippet below.
Matching err != nil would also wrongly match the second if statement.
Providing a line numbers range could be a way to handle cases like this correctly.

enabled, err := exp.BoolValue("enabledFlag")
if err != nil {
    // ...
}

disabled, err := exp.BoolValue("disabledFlag")
if err != nil {
    // ...
}
