From d6576e1fe3ee4bd7bd2cf01d17499c94da24876f Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Sat, 13 Feb 2010 22:28:28 +0100 Subject: [PATCH] builtin-notes: Add "prune" subcommand for removing notes for missing objects "git notes prune" will remove all notes that annotate unreachable/non- existing objects. The patch includes tests verifying correct behaviour of the new subcommand.
