commit 999fb37ebb1aecfda9889fa6a2b2fbb15133f2aa
Author: Jean-Marc Lasgouttes <lasgout...@lyx.org>
Date: Sat Jul 20 22:31:34 2024 +0200
Do not run updateMacros if the buffer has not changed
Each buffer now has an id which is increased when it is marked dirty
(or when one of its relatives is marked dirty).
This can be a big win since updateMacros is very expensive.
