Subject: bug#18024: 24.4.50; doc of `y-or-n-p' misses the main functionality: what it returns
Date: Tue, 15 Jul 2014 08:23:54 -0700 (PDT) [thread overview]
Message-ID: <11537e47-82da-4913-9f97-8afb105bdada@default> (raw)
1. `y-or-n-p' is a *predicate*. This is missing from the doc string,
because it says nothing about what the function returns if the user
answers `n' instead of `y'. The doc string *must* tell users that `n'
means return nil.
2. The Elisp manual does not have that failing. However, to be clear,
both it and the doc string should specify that *whatever* way the user
answers in the affirmative means return `t', and *whatever* s?he answers
in the negative means return `nil'. Currently the manual specifies the
return value only for `y' and `n'.
