Comment (by molinerozadkiel):

 use case for "posts_per_page" => 0 to display no posts:

 I am building a ajax search bar in a header, I have all the logic already
 done and working from older projects, but in this case the designer had
 the brilliant idea to show no posts if the search bar is empty (because
 the results are shown within the header, so is good to now show anything
 if the user is not looking for something so that is won't produce visual
 clutter)
 So, I would like to jus be able to pass a 0 there when the search bar is
 empty...

 Besides, "0 to show 0 posts" makes sense, and not doing it like this makes
 the system more prone to errors and harder to debug, as stated by other
 users before.
 0 counts as "False" in many cases so I imagine the problem is problbly
 comming from there somehow
