If you know the length of the program name, why do you need to search for the
next space character?

No tests for this?

I think it's possible that there could be a trailing double-quote.
None so far. Now is as good a time as any to add some. I'll send up another
patch set with some.

     cmd_to_append = tmp;
   }
