This passes inside a *.t file (still requires ui.slash debugwalk patch):

  $ hg init t
  $ cd t
  $ mkdir -p "bea;ns"
  $ for b in kidney navy turtle borlotti black pinto; do
  >     echo $b > "bea;ns"/$b
  $ done
  $ hg addremove
  adding bea;ns/black
  adding bea;ns/borlotti
  adding bea;ns/kidney
  adding bea;ns/navy
  adding bea;ns/pinto
  adding bea;ns/turtle
  $ hg commit -m "commit #0"

  $ mkdir mammals
  $ cd mammals
  $ hg debugwalk -I 'relpath:../bea;ns'
  f  bea;ns/black     ../bea;ns/black
  f  bea;ns/borlotti  ../bea;ns/borlotti
  f  bea;ns/kidney    ../bea;ns/kidney
  f  bea;ns/navy      ../bea;ns/navy
  f  bea;ns/pinto     ../bea;ns/pinto
  f  bea;ns/turtle    ../bea;ns/turtle
