[aur-dev] [PATCH 2/4] Check query return value in search_results_page()

[Lukas Fleischer]

Instead of unconditionally calling fetch on the return value of query(),
error out early if the value evaluates to false. Also, make sure that
the results array is always initialized, even if the result set is
empty.
