How does it interfere with the compilation-mode more concretely?

By definition next-error(M-g n)/previous-error(M-g p) operate on the
most recent buffer (in buffer-list) that contains `next-error-function`
and is complete unrelated to compilation mode. If you just called
`occur` you navigate in *occur* buffer, grep - in *grep*, compile - in
*compile* etc.

IMW *xref* is conceptually closer to *compile* than to *occur* or even
*grep* buffers.

Dmitry, would you mind putting this back?

Thanks,
