ls-tree: test for the regression in 9c4d58ff2c

Add a test for the regression introduced in my 9c4d58ff2c (ls-tree: split up "fast path" callbacks, 2022-03-23) and fixed in 350296cc78 (ls-tree: `-l` should not imply recursive listing, 2022-04-04), and test for the test of ls-tree option/mode combinations to make sure we don't have other blind spots. The setup for these tests can be shared with those added in the 1041d58b4d (Merge branch 'tl/ls-tree-oid-only', 2022-04-04) topic, so let's create a new t/lib-t3100.sh to help them share data. The existing tests in "t3104-ls-tree-format.sh" didn't deal with a submodule, which they'll now encounter with as the setup_basic_ls_tree_data() sets one up. This extensive testing should give us confidence that there were no further regressions in this area. The lack of testing was noted back in [1], but unfortunately we didn't cover that blind-spot before 9c4d58ff2c. 1. https://lore.kernel.org/git/211115.86o86lqe3c.gmgdl@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
