From 894a9d333e9e2015cad00d95250b7c5d3acea8b6 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Fri, 12 Mar 2010 18:04:26 +0100 Subject: Support showing notes from more than one notes tree With this patch, you can set notes.displayRef to a glob that points at your favourite notes refs, e.g., [notes] displayRef = refs/notes/* Then git-log and friends will show notes from all trees. Thanks to Junio C Hamano for lots of feedback, which greatly influenced the design of the entire series and this commit in particular.
