Among the current callers, the one in builtin/tag.c that wants to
trigger show_tag_lines() hack embedded in show_ref_array_item()
function can stop calling show_ref_array_item() and instead can do
for (i = 0; i < array.nr; i++) {
struct strbuf out = STRBUF_INIT;
format_ref_array_item(&out, ...);
if (filter->lines) {
... append tag lines to out ...
}
printf("%s\n", out.buf);
strbuf_reset(&out);
}
The current and future callers of show_ref_array_item() that do not
want to trigger the show_tag_liens() hack embedded in there may
still want it to print the formatted string including the trailing
LF, so you can keep show_ref_array_item() as a thin wrapper around
format_ref_array_item() for them to call, e.g.
show_ref_array_item(...) {
struct strbuf out = STRBUF_INIT;
format_ref_array_item(&out, ...);
printf("%s\n", out.buf);
strbuf_release(&out);
}
But if it has only one caller each, you may not even want to have
show_ref_array_item(), if you are going to do the "output to strbuf"
variant.
