From d153ca75d0323eb125e525ebdf4ac5c982941d15 Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Tue, 15 Oct 2019 16:26:30 -0400
Subject: [PATCH 56/86] Improve consistency of debug prints
This changes debug prints in a couple of ways:
- always calls the path we're parsing "current" in the output
- always use ' not " for quoting in the debug output, so tools that
escape strings won't change the lenghts
- everything that parses "current" has a debug print after each parse
attempt and before returning.
