The following is a patch to fix this.

In the case of ruby, the current _ruby contains
  '(-)1:script file:_files'
This means all files (foo.rb, bar.py, junk.c, etc.) are
offered as Ruby scripts, but I didn't change this in the
patch. I have no experience with ruby and don't know
what most ruby users expect here.
