This gets rid of the repeated magic string length constant 2, which is
nice. But why not go all the way to full strbuf-ness? It's shorter,
looks less busy, and the extra two copied bytes shouldn't matter in a
measurable way.
else {
strbuf_reset(buf);
strbuf_addstr(buf, n->tip_name);
strbuf_strip_suffix(buf, "^0");
strbuf_addf(buf, "~%d", n->generation);
return buf->buf;
}
