Generalize % operator: Handle 100+10% as expected

Bug: 22836179

Handle + or - operators specially if they are followed by a constant
or pre-evaluated expression and the % operator.

Since this is basically an idiomatic use of the operators, we
apply it very conservatively.  When in doubt we use the old
interpretation.

Also fixes one unrelated anachronism in a comment.
