Answering this after every next-error command would be too tedious for users,
and it's not clear how to reduce the frequency of such questions, i.e.
how to detect only dubious cases.

Recently we created such command with the name ‘next-error-select-buffer’.
Still too inconvenient for users to run this command explicitly.
We need next-error to be more DWIM.
