Subscriber class documentation is lacking in a couple of places

API page: https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21EventSubs...

Enter a descriptive title (above) relating to class PathSubscriber, then describe the problem you have found:

The PathSubscriber class has only one line of documentation and it appears to have been copy/pasted from another class. It's totally wrong.

It needs to be replaced with a line documentation that says what it actually does, which is to translate path aliases.

I think this is actually a good novice project.
