It's unintuitive or at least inconsistent because other functions
(e.g. `char-after') treat the high edge of a narrowed buffer as though
it were the actual end of the buffer.

For an example of where this is problematic, look at the patch I
submitted last night on this list.  I was patching functions that use
the text property search functions and had to make a special case for
where point is at (point-max) and the buffer is narrowed.
