I think the problem occurs only because compilation/grep pop up their
output buffer in another window - this creates ambiguity whether to use
navigation from the current buffer or from another (new) buffer.

It seems there is no right answer suitable for all users.  So I propose
to add more options.

Eli, do you agree with adding more options to `next-error-find-buffer-function'
in emacs-27?

Currently it has one option that defines one of possible behaviors existed
in older versions.  Now we need to add other option for compatibility
with pre-27 versions.

Then users of emacs-27 could decide whether they want to keep
the old behavior or use the new.

I'm not sure about the default value: should it default to pre-27 behavior.
