net/http: Documentation: type ResponseWriter interface

[SickAustrian]

I have found a small error in the type ResponseWriter interface documentation. As part of the server.go file the following is stated:

// To suppress implicit response headers (such as "Date"), set
// their value to nil.
Header() Header

However, Header is of type type Header map[string][]string which means headers can only be overritten using the empty string "". To avoid any confusion, the documentation should hence be changed accordingly:

// To suppress implicit response headers (such as "Date"), set
// their value to "" (empty string).
Header() Header

The docs are correct.
