Miscellaneous tweaks:

1. Simplified the logic in searchValueTransform().

2. In a debug message: changed format specification to %p for pointer
values, instead of %d.  Using %d will garble the output if ints and
pointers don't have the same size (and they don't on my laptop).

3. Corrected a typo in another message. The word "non-existant"
is non-existent.

4. For clarity: in several places, reversed the logic of some
if/elses so that we test for a positive condition instead of
a negative condition.
