That did it! Here's what I did. I need to not just turn the hyphen into 
range dots, but, I also need to get rid of any commas and stuff between 
input entries.
ARGV.each do |f|
  f = f.gsub(/-/, "..")
  f = f.gsub(/,/, "")
  puts f
end

So, here's my input:
  test1.rb im145000-145004, im145006, im145009

I get:
  im45000..im145004
  im145006
  im145009

Phew. Thanks, everyone. Now I'm going to work on breaking down that 
range into its elements, but, I think I can handle that.
