76 * those of create_branch() except for start_name, which is represented
77 * by two different parameters:
78 *
79 * - start_committish is the commit-ish, in repository r, that determines
80 * which commits the branches will point to. The superproject branch
81 * will point to the commit of start_committish and the submodule
82 * branches will point to the gitlink commit oids in start_committish's
83 * tree.
84 *
85 * - tracking_name is the name of the ref, in repository r, that will be
86 * used to set up tracking information. This value is propagated to
87 * all submodules, which will evaluate the ref using their own ref
88 * stores. If NULL, this defaults to start_committish.
89 *
90 * When this function is called on the superproject, start_committish
91 * can be any user-provided ref and tracking_name can be NULL (similar
92 * to create_branches()). But when recursing through submodules,
93 * start_committish is the plain gitlink commit oid. Since the oid cannot
94 * be used for tracking information, tracking_name is propagated and
95 * used for tracking instead.
