  test-yesno: work around sparc-dash here-document infelicity
  
  Without this change, the literal \177 byte in a here document
  would make dash 0.5.5.1-3 access uninitialized memory.
  * tests/test-yesno.sh: Don't put the \177 byte in the here document.
  Instead, use a marker, "@", and filter through tr to create the desired
  contents.  Reported as <http://bugs.debian.org/548493> by Kurt Roeckx.
