Thanks. However, that new test would never run, because the new file's
name was not listed in tests/Makefile.am.  I added it, and changed the
test script to merge two loops (avoiding some duplication) and
improved comments (this also affects 2.19). I also tracked down the
commit that introduced the problem and listed it in the commit log,
and mentioned in NEWS that both 2.19 and 2.20 were affected. I changed
the commit log to provide more detail: this is important, especially
for a bug fix.  Simply saying "fixed the bug" does not help the reader
understand.  One must say how/why the code failed, and/or what changed
to make it work, especially when the change is nontrivial.
