[Swan-dev] pointless test failures

| Yes, I wasn't sure yet if we would leave it in like that but I guess we
| should, and update the reference output.

Reference output should change in sync with program output change.  
Either both in, or both out.  Mismatch is not a reasonable state.  If it 
is a bug, don't change the reference output, change the code.  But 
eliminating divergence should be a priority: it is a kind of 
build-breaking.

| output gathering bug that stopped showing me the test output graphics.

The run is still quite useful.  testing/utils/pluto-testlist-scan.sh
still works.  That's what I used to find the problems I reported.

BTW, the number of useless test failures seems quite a bit better than
I remember.  Everyone: thanks for all the work so far.
