This make `SPC h SPC` as default binding for accessing `helm-spacemacs`, by either A) changing all the documentation; and B) adding a deprecation message for `SPC f e h`. The deprecation use a warning, because if a message is used it's hidden directly when the helm buffer is shown, making it nearly unnoticeable for the user.

GO layer
Description
This layer adds extensive support for go.
Features:
- gofmt/goimports on file save
- Auto-completion using go-autocomplete (with the
auto-completionlayer) - Source analysis using go-oracle
Install
Pre-requisites
You will need gocode and godef:
go get -u -v github.com/nsf/gocode
go get -u -v github.com/rogpeppe/godef
go get -u -v golang.org/x/tools/cmd/oracle
go get -u -v golang.org/x/tools/cmd/gorename
Make sure that gocode executable is in your PATH. For information about
setting up $PATH, check out the corresponding section in the FAQ (SPC h SPC
$PATH RET).
For best results, make sure that the auto-completion and syntax-checking
layers are enabled as well.
Layer
To use this contribution add it to your ~/.spacemacs
(setq-default dotspacemacs-configuration-layers '(go))Configuration
Formatting
By default, go buffers are run through gofmt on save. To use a different
formatter, set the value of gofmt-command, e.g.
(setq gofmt-command "goimports")or
(go :variables gofmt-command "goimports")
If you're using gocheck in your project you can use the
go-use-gocheck-for-testing variable to enable suite testing and to get single
function testing to work.
