Without this it would not go there with an already open qf window, and
would go to an unexpected buffer line instead of selecting the entry.
This is a follow-up to b689409, where it was decided that it should
always require the user to select an entry.
An exception is when the same usages are used again: then it will select
the nearest/current entry only (via ":cc").
