Hm - it does a diff with (basic, alt) files. If all diffs fail - then it prints a diff from one of them.

I'm not sure how this works with alt files. I assumed it ignores alt
files - and updates the primary file.  Usually I would need a new alt
file - so I just move this over manually to a new one [and keep the
current files unchanged]

Note: To test the new alt file - one need to do 'make cleantest' and
rerun the test - otherwise the test harness does not know that it
should pick up the new alt file.
