The present failures started much more recently than f8f4afe ...
leafhopper, for example, was okay until about a day ago.
Also, AFAICS f8f4afe was HEAD-only, but leafhopper is also
failing in v18. (No evidence as yet about older branches.)
Anyway, this is exactly the sort of analysis that we shouldn't
be doing.
