19 | * The util field of our string_list_items will contain one of two things: | |
20 | * | |
21 | * - if --summary is not in use, it will point to a string list of the | |
22 | * oneline subjects assigned to this author | |
23 | * | |
24 | * - if --summary is in use, we don't need that list; we only need to know | |
25 | * its size. So we abuse the pointer slot to store our integer counter. | |
26 | * | |
27 | * This macro accesses the latter. | |
