Subject: [PATCH] Support changing autoreload option directly from the reload
 message

Pressing Y or N will set the buffer (or window, if it is set at that
scope) autoreload option to the corresponding value, avoiding infinite
loops where a file getting constantly modified prevents the user from
using Kakoune.
