From fb2b9815a4b5ea04a5f08940f546c6d5ef5e2414 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Fri, 6 Sep 2024 20:22:35 +0000 Subject: [PATCH] advice: recommend GIT_ADVICE=0 for tools The GIT_ADVICE environment variable was added implicitly in b79deeb5544 (advice: add --no-advice global option, 2024-05-03) but was not documented. Add documentation to show that it is an option for tools that want to disable these messages. Make note that while the --no-advice option exists, older Git versions will fail to parse that option. The environment variable presents a way to change the behavior of Git versions that understand it without disrupting older versions.
