If someone configures a 'textwidth' in go files, vim will by default insert
newlines into long lines as you type, which breaks syntax and doesn't really
make sense for go code. This fixes the default.

This basic Vim ftplugin sets the 'comments' and 'commentstring'
settings to sensible values. Future filetype settings for Go
would go in the same file.
The ftplugin was added as misc/vim/ftplugin/go/go.vim, this way
the installation instructions in readme.txt remain valid.
Fixes#5715.
