Previous D/F fixes I submitted (5a2580dandae74548) had caused merge to become excessively spammy, which was fixed in96ecac6(merge-recursive: Avoid excessive output for and reprocessing of renames 2010-08-20). Add a new test to avoid repeating that mistake with my several upcoming changes. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
