 This patch partially solves the problem when there is only short option
 name for the parameter and option_description class generates ugly help
 message. For example -

 `{{{(",w", po::value<int>(), "Perfrom write with N frames")}}}`

 generates this

 `{{{-w [ -- ] arg : Perfrom write with N frames}}}`

 The "[ -- ]" part is confusing. So if long option name is empty, we don't
 print that part.

 Ideally, we should also print one dash for single character long option
 name if command_line_style::allow_long_disguise is specified, but I can't
 find a way to access those styles from option_description.

 Originally, the problem found by a guy at Stack Overflow -
