x/tools/cmd/goimports: doc lists out-of-date go-mode.el configuration

https://godoc.org/golang.org/x/tools/cmd/goimports

It says to add the following to .emacs:

(setq gofmt-command "goimports")
(add-to-list 'load-path "/home/you/somewhere/emacs/")
(require 'go-mode-autoloads)
(add-hook 'before-save-hook 'gofmt-before-save)

go-mode-autoloads is no longer used by go-mode (see dominikh/go-mode.el#222), and this line will probably produce an error. That line should be removed.

Also, I found the add-to-list line confusing, because it's not clear from context whether this is optional or required. Might be good to remove that, and then say something like "This searches load-path for goimports, so you may need to add the goimports location to load-path." (Sorry for this separate issue. Feel free to tell me to break it out to a separate issue if it's too large or controversial.)

Really, the only line that is necessary is the first one. Emacs users will already have done all of the other necessary steps to get go-mode working.

This was fixed in golang/tools@1c3d964, so I'm closing this issue.
