Based purely upon my own idiosyncratic interpretation, I came to the
conclusion that I would use building=terrace for a row of terraced houses
where I did not have the time to ascertain the numbers on a survey or
was working from aerial imagery.  I view it as a placeholder.  There are
some house there but I don't know where the individual boundaries are
and I can only give you a range of addresses, if that.

Then, after having replaced a terrace mapped by somebody else with
individual houses, I came to the conclusion that I wouldn't bother mapping
things as terraces - too much effort for too little gain if I intended to
replace them at a future date.

I see no point in wrapping individually-mapped houses in a terrace.  If
they're conjoined then it's already obvious that they're part of a terrace.
