I wondered why my neovim was slow. Turned out notmuch.vim loading took >
500ms to load (ruby and all). And I dont even use it !
I suspect the plugin could be improved to lazyload more stuff but I
think it's ok to have the vim plugin installer be a user decision as well.
I moved it to a new "vim" output : you can install the plugin via
"notmuch.vim"
