From 3b18ea9139a1bdd9183db6f3ac6d174ad93b3cb3 Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Sun, 24 Apr 2022 13:38:46 +0000 Subject: If a .shift request has a negative argument, do not use a negative array index but use 0 instead of the argument, just like groff. Warn about the invalid argument. While here, fix the column number in another warning message.
