The is_descendant_of method takes a single commit as its first parameter and a list of commits as its second parameter. Extend the input of the 'test-tool reach' command to take multiple lines of the form "X:<committish>" to construct a list of commits. Pass these to is_descendant_of and create tests that check each result. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
