Subject: Factor pushMatchingRanges, improve comments/tests 1. Factor out
 `pushMatchingRanges`:    This then allows us to ... 2. Add unit tests for
 `pushMatchingRanges`    In effect, these tests verify where matches are
 highlighted in suggestions. 3. Added Utils.zip.  This helps simplify
 `pushMatchingRanges` unit tests. 4. Improve comments.
