That is a very good sign why this change is merely a code-churn and
not an improvement, isn't it?  We know (and any strbuf user should
know) that ->buf and ->len are the ways to learn the pointer and the
length the strbuf holds.  Why anybody thinks it is benefitial to
introduce another function that is _only_ for writing out strbuf and
cannot be used to write out a plain buffer is simply beyond me.
