Good point.  I will add string-cursor? with specific language saying
that it may return either #t or #f on objects that are neither cursors
nor indexes.

Let's face it: software is crap. Feature-laden and bloated, written under
tremendous time-pressure, often by incapable coders, using dangerous
languages and inadequate tools, trying to connect to heaps of broken or
obsolete protocols, implemented equally insufficiently, running on
unpredictable hardware -- we are all more than used to brokenness.
