Comment (by Polyergic):

 AFAIK if could just be a documentation problem.  The description of `-N`
 doesn't read like it assumes the answer to that question would be yes, but
 apparently that's what it does.  That could be made clear.  It's also not
 clear what other interactive prompts might occur during an install and
 what answers `-N` would assume for them.  If there aren't any, `-N
 install` does what I want, it's just not documented clearly.

 But `-N` meaning "Assume Yes answers to some interactive questions" is
 weird enough that I'm not sure clarifying the documentation will cover all
 the problems; what if someone wants to assume No to installing
 dependencies?  What I was imagining initially was an option that might
 have a long form like `--yes-install-dependencies` or `--install-
 deps=yes`, which would non-interactively answer just this one question, or
 `-R` meaning `--recursive`.
