 Currently, `man port` has the following:
 {{{
        -N
            Non-interactive mode, interactive questions are not asked
 }}}
 It would be nice if this could be clarified to better specify how exactly
 it behaves when the questions aren't asked. I'm assuming that it means
 that the behavior is as if the user just chose the default response to all
 questions? I'm wondering because I've been thinking that it might be nice
 to split the flag into 3:
 - 1 that removes interactivity by assuming that the response is always
 "yes"
 - 1 that removes interactivity by assuming that the response is always
 "no"
 - 1 that removes interactivity by assuming that the response is whatever
 the default is (which is what I'm assuming the current behavior is)

 Also, a conf option and/or environment variable to control this behavior
 would both be nice, too (primarily for CI systems).
