options: allow choice options without parameter
If an m_option_type_choice option is declared with M_OPT_IMPLICIT_DEFAULT
in its flags, it doesn't require a parameter. For example, if --opt is
such an option, it can be invoked as "--opt=val", "-opt", or "--opt".
The last two will set the option to the first choice the option declares.
Note that "-opt val" (using the old option syntax) is not allowed in this
case, as it would be ambiguous.
Normal option parsing should be unaffected.
