What strbuf variable renamed to what?
I have a feeling that squashing this and 3/6 into a single patch,
and pass buf.buf and buf.len to the new helper function without
introducing an intermediate variables in the caller, would make the
resulting code easier to follow.
In any case, nice factoring out of a useful helper function.
