fix spacing on last line of 'help' text

I may have messed up, I can't seem to find the description of this issue in here so let me try again...

a minor thing, but right now when I do:  cf push --help      the last line is just a set of 3 spaces w/o a CR. This means that my cmd line prompt is indented:

   --no-hostname	Map the root domain to this app
   --no-manifest	Ignore manifest file
   --no-route		Do not map a route to this app
   --no-start		Do not start an app after pushing
   --random-route	Create a random route for this app
   dugmb:~/work>

kind of funky. A minor tweak is needed to the help text template to fix it.
