[help-gengetopt] multiple default values not possible it seems

[Erik Sjölund]

Multiple default values are not supported it seems. If you for instance 
specify

option "weights" w  "some text" typestr="FLOAT,FLOAT" float 
default="2.0,2.0" optional multiple(2)

I get "invalid default value".

I would be nice if that could be supported. If not I would suggest 
adding some more documentation, for instance like
the attached patch.

cheers,
Erik Sjölund
