Thanks for the fixes.

As for "pair", it's actually a cons cell, right?  Also, we do tend to
use the phrase "of the form ..." in our documentation, so there's no
need to remove that.

Finally, a nit: "Point position" is inherently ambiguous, so it's
better to use "Position of point" to disambiguate.  I made that change
in a followup commit.
