It looks like it'll work just fine as long as you don't
put quotes around `bison -y'.

  $ printf '%%%%\na:\n%%%%\n' > j.y
  $ sh missing --run bison -y j.y

Hmm... at first I thought it was independent of the actual value,
but just tested it and see that it may indeed be specific to `:':

  $ p=:
  $ "$p"
  º: not found
  $ p=echo
  $ "$p"
