In Danish, the sequence 'aa' is sometimes treated as a single letter
which collates after 'z'.
Some regression tests got into 9.5, and are still in 9.6beta3, which
fail due to assuming they know how things will sort or compare.
I thought the easiest way to deal with it was just to change the test
data to use 'ab...' rather than 'aa...' to represent an
early-collating string.
With these applied, this now passes:
LANG=danish make check
