If you make only the code changes, there are a bunch of diffs stemming
from the removal of the 'error in steps' message prefix.  If you just
mechanically remove those from the .out files without touching the .spec
files, most tests pass, but I don't recall whether that's 100% the case.

I'll have a v2 in a little bit --- the cfbot pointed out that there
were some contrib tests I'd missed fixing, and I found a couple of
other improvements.
