[PATCH] blame: Add tests for -L/start/,/end/

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

git-pickaxe (later git-blame) gained support for the -L/start/,/end/
form in 2006 (931233bc66 by Junio C Hamano), but nothing was added to
test this functionality. Change that by adding more -L tests to
t8003-blame.sh.
