> [~rcmuir] noticed that {{Lucene60PointReader}} does not detect truncation of its data file on reader init ... so I added a test to catch this, confirmed it caught the bug, and fixed the bug, and fixed a couple other things uncovered by the test.
> I also improved the other {{TestAllFiles*}} tests to use {{LineFileDocs}} so they index points, and it caught another bug in {{Lucene60PointFormat}} (using the same codec name in two files).
> There is more to do here, e.g. we also need a test that catches places where we fail to check the index header on init, which was also missing for {{Lucene60PointReader}}.
