test(mutants): the cursor rule's row clause and the end-of-line clause get a mutant each

Browse source 
The catalogue goes 45 to 47 and the runner stays `killed N of N`, exit 0.

`P8` is PM's own survivor from `44ad845`: the cursor rule one row too lenient
(`height - 1` -> `height - 2`), which survived 51 tests because no arm in
`CURSOR_CASES` stopped a row early. `P13` removes the clause this round added,
so the round leaves a mutant behind and not only a test. Both are judged by
`tests/test_asset_viewable.py`, which is why the per-mutant suite added in the
previous round was worth having.

CHANGELOG under 0.10.1, no new version and no tag.
