char-after is a primitive, and it behaves intuitively at (point-max) on
narrowed buffers.  Why shouldn't other functions behave consistently?

Nevermind about the search functions.  I was confused about the behavior
of previous-single-property-change.  The problem lies in the functions
that fetch the properties.
