some issue on macos with cp command

[atom992]

if syntax or ftdetect or doc directory doesn't exists on ~/.vim

cp n1ql-vim/syntax/n1ql.vim ~/.vim/syntax

will not create ~/.vim/syntax directory. instand, syntax file will be created.
so the cp command should be

cp n1ql-vim/syntax/n1ql.vim ~/.vim/syntax/n1ql.vim
