Ah, the semantics of ONLY_STANDARD_ESCAPES was what I was
missing - even though you correctly mention it in the
test-case!  (If there had been a bug, it would have been ok
to say that any bug here was pre-existing and you correctly
handle that by xfailing it. :-)

For me, at a09771e687ba z80-elf and cris-elf pass that test
and also run gas, binutils and ld tests without errors.

Thanks for resolving this so quickly!
