" does it accept only long options?

Not really, it also accepts short options, but it "prefers" long ones in a way 
that '-' as well as '--' __can__ introduce
long-named options. It checks first if the commandline argument starts with a 
long option or its unique abbrevation, if the first alphanumeric character does 
not match any of the short option characters.

A short excerpt from the GNU getopt1.c:

/* Check whether the ARGV-element is a long option.

     If long_only and the ARGV-element has the form "-f", where f is
     a valid short option, don't consider it an abbreviated form of
     a long option that starts with f.  Otherwise there would be no
     way to give the -f short option.

     On the other hand, if there's a long option "fubar" and
     the ARGV-element is "-fu", do consider that an abbreviation of
     the long option, just like "--fu", and not "-f" with arg "u".

     This distinction seems to be the most useful approach.  */
