I reproduced this with LC_ALL=en_US.utf8 and LC_ALL=C.UTF-8;
it looks like a bug in processing UTF-8. (BTW GNUN doesn't
pass 'make installcheck').

A smaller test case is

echo 'abcdefgh "014"' \
  | sed 's%.*%&\na%;s/^abcdefgh "\([^\n]*\)"[^\n]*\n/\1\n/'

Perhaps GNUN should always invoke sed with the C locale.

I'm just curious what the "-2" is for.
