(info "(emacs) Other Repeating Search") says what is the recommended way
to do this is:
`M-x occur'
Prompt for a regexp, and display a list showing each line in the
buffer that contains a match for it. The text that matched is
highlighted using the `match' face. To limit the search to part
of the buffer, narrow to that part (*note Narrowing::).

The name occur-backward falsely implies it uses re-search-backward,
and I'm unsure if we need it as a counter part of isearch-backward.
> 2) occur-forward: for lines after the current one.

Maybe we should use the same logic of other related commands in replace.el
how-many, keep-lines, flush-lines that limit the affected lines to the
active region, or when the region is not active, take only lines after
the current line. Then we don't need separate commands, and no keys for them.
