From da99bb0bcd8c92e0d6de8b929b67095fae251f88 Mon Sep 17 00:00:00 2001 From: "Scott L. Burson" Date: Fri, 14 Nov 2025 15:16:57 -0800 Subject: [PATCH] diff: "lisp" userdiff_driver The "scheme" driver doesn't quite work for Common Lisp. This driver is very generic and should work for almost any dialect of Lisp, including Common Lisp. Signed-off-by: Scott L.
