Add GoLang syntax highlighting for VIM

Go 1.4 Release Notes

Miscellany

The standard repository’s top-level misc directory used to contain Go
support for editors and IDEs: plugins, initialization
scripts and so on. Maintaining these was becoming time-consuming and
needed external help because many of the editors listed were not used
by members of the core team. It also required us to make decisions
about which plugin was best for a given editor, even for editors we do
not use.
The Go community at large is much better suited to managing this information. In Go 1.4, therefore, this support has been removed from
the repository. Instead, there is a curated, informative list of
what’s available on a wiki page.

The standard Go distribution includes Go files for Vim in go/misc/vim/. This directory contains a readme.txt file which contains installation instructions.

Vim plugins for Go (http://golang.org)

To use all the Vim plugins, add these lines to your $HOME/.vimrc.

" Some Linux distributions set filetype in /etc/vimrc.
" Clear filetype flags before changing runtimepath to force Vim to reload them.
filetype off
filetype plugin indent off
set runtimepath+=$GOROOT/misc/vim
filetype plugin indent on
syntax on

If you want to select fewer plugins, use the instructions in the rest
of this file.
