No need to wait.  Consider that anyone using apr_file_gets() already expects
to have an EOF.  The question is if they are prepared to read data.

As long as we give them no data I believe the change won't break any
applications.  So ++1 since this is an easy app bug we can help to

The only risk is users who might use data+EOF to check for missing \n.
This would be a silly side-effect dependency, but it belongs in CHANGES
just in case anyone had done so.
