From 92b3385fca620f47580d695b80b96432c76f0822 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Sat, 13 Feb 2010 22:28:25 +0100 Subject: [PATCH] builtin-notes: Add "remove" subcommand for removing existing notes Using "git notes remove" is equivalent to specifying an empty note message. The patch includes tests verifying correct behaviour of the new subcommand.
