Subject: [PATCH] Fix shell startup time

makes nvm a function that gets replaced by the real nvm function.
After that, it will get called with the specified arguments. Calls
after this initialization call, will use the original nvm shell
function. By introducing this indirection, shell startup time is
significantly improved.
