This patch adds testcases verifying correct behaviour in several scenarios regarding fast-import of notes: - using a mixture of 'N' and 'M' commands - updating existing notes - concatenation of notes - 'deleteall' also removes notes - fanout schemes is added/removed when needed - git-fast-import's branch unload/reload preserves notes - non-notes are not clobbered in the presence of notes Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
