Misleading minus signs in Cucumber progress format

I have been recently using the Ruby test tool Cucumber and came across a little annoyance.  In the progress format output there were unexpected minus signs:

  $ cucumber --format progress features/codebreaker_submits_guess.feature
  ---..........................................
  14 scenarios (14 passed) 42 steps (42 passed)
  0m0.117s 
  $

Normally minus signs would be used to indicate skipped steps but here they seem to be displayed for each scenario outline step whether it is skipped or not.

A little Googling revealed that this is a known bug that has not yet been fixed because of the awkward internal design of Cucumber.
