From af74128f4a447678daae4d59069fba8a0c797210 Mon Sep 17 00:00:00 2001 From: Ralf Thielow Date: Fri, 26 Aug 2016 19:58:35 +0200 Subject: [PATCH] help: introduce option --exclude-guides Introduce option --exclude-guides to the help command. With this option being passed, "git help" will open man pages only for actual commands. Since we know it is a command, we can use function help_unknown_command to give the user advice on typos.
