Shouldn't getopt_long() return : here?

This is your problem.  You need to have ':' as the first character in 
short_options, if you want the behavior you describe.  (Also, if you 
plan to handle errors -- including printing the error message yourself 
-- you need to set the global variable opterr to 0)

So, you need
     const char *short_options = ":";
     /* opterr = 0; */ /* maybe */
