Let me make sure I understand the problem and solution.

When next-error is called in buffer X, it may pop the user into
buffer Y.  We want to unset next-error-function in Y, so that
next-error does not act in Y from that point on.

Couldn't this be achieved by making the next-error-last-buffer check
in next-error-find-buffer precede the current-buffer check?

We need to define a function next-error-follow-this-buffer that would
set next-error-last-buffer to (current-buffer).  That way, users can
force the behavior that now is the default, that next-error should act
on (current-buffer) first and foremost.  I would bind
next-error-follow-this-buffer to C-x ~ (which on US keyboards is
Shift-` so remembering it is not too bad).
