This is a genuine failure, so you're creating a <failure> node. Okay.

This was expected to fail but didn't, which means it probably needs
some sort of attention. test_known_broken_ok_() prints this result in
the 'error' color, and test_done() re-inforces that by printing a
message, also in 'error' color:

    42 known breakage(s) vanished; please update test(s)

So, should this emit a <failure> node also, perhaps with 'type'
attribute set to "warning" or something? (<failure type="WARNING"
message="...">)

It's possible to insert a literal CR in the 'sed' expression, which
does match correctly on BSD (and MacOS). For instance:

    CR=$(printf "\r")
    sed -e "s/$CR/\&#x0d;/g"
