Re-fix some warnings about mixing signed and unsigned better...

Browse Source 
... Assuming that large unsigned magnitudes with high order bit set are not
the problem, but signed negatives of small magnitude may be:

1) Always cast the unsigned to signed in comparisons, not the other way.

Also:

2) Cast unsigned TERM to signed by itself, before subtracting.  Don't cast
the result.

3) Rewrite some comparisons by moving subtracted term to other side.
