For all fairness, when the WIDTH thing was introduced, there were
two places that needed reference it at f1863d0d16 ("refactor
duplicated code in builtin-send-pack.c and transport.c",
2010-02-16). But that is no longer the case, and it makes sense to
hardcode it as 17 (or something derived from a symbolic constant
that gives the new "default to default").
What TRANSPORT_SUMMARY() does is even more crazy and it really
shouldn't be exposed as a public interface. Let's move it to its
single calling place.
