    Improve module parameter completion
    
    First, do not embedd the = in the parameter by define it a
    parameter‐value separator; -S =.
    
    Second, look for already given parameters in all words; -w.
    
    Third, use the curcontext variable; -C.
    
    Forth, distinct between boolean and non‐boolean parameters, i.e. do not
    append a = to the end. And include the type of the parameter in the help
    message. This information is only given in the full output of modinfo,
    not in the narrowed output with --field.
