Multiple Godoc buffer

[koron]

Currently :Godoc opens a document in single buffer.
But I want to open documents in multiple buffers sometimes.

How about use :Godoc! to open a document with a new buffer.

:Godoc net/http
" open net/http

:Godoc crypt/tls
" reuse previous buffer and open crypt/tls

:Godoc! net/http
" open net/http with new buffer
