 When using a long option with a '''hyphen''' in its name, the error string
 does not output the option name, but rather the substring from the
 rightmost hyphen position.

 Example: option foo-bar with double.
 {{{
 ./myprogram --foo-bar nonumber
 }}}

 Since "nonumber" cannot be cast into double, it throws an exception.
 The error message is:
 {{{
 "the argument ('nonumber') for option '--bar' is invalid"
 }}}

 Option name is wrongly quoted as '''"--bar"'''. Expected is '''"--foo-
 bar"'''.

 Check the attached example for reproduction. See the attached patch fixing
 the bug. SVN rev 82783.
