I didn't know that. Are those cases obscure?

Not just comments though it can be anything. For example, put the
following in prolog-mode. Move point to the first `{' char and then M-x
indent-sexp.

iso_time(Hr, Min, Sec) -->
    hour(H),
    timezone(DH, DM, DS),
    { Hr is H + DH, Min is DM, Sec is DS }.

timezone(Hr, Min, 0) -->
    "+", hour(H), ":", minute(M), { Hr is -1 * H, Min is -1 * M }.
