From db683b285cfb31deb9dbdafbc5a18e0b471ffa65 Mon Sep 17 00:00:00 2001 From: Marcel de Rooy Date: Fri, 21 Sep 2018 09:15:08 +0200 Subject: [PATCH] Bug 21281: (QA follow-up) Introduce _add_backtics Added a (initially trivial) test in Creators/Lib.t too. Sometimes you start something, but you end somewhere else ;) The test seems a bit slower now (regex, lookahead, etc). But this should not hurt label creators in daily use. Advantages: code is even more solid, consolidated in one place and can be tested on its own.
