Re: feature request: ability to use occur within *Occur* buffer

[Michael A. Patton]

I think that I've previously used M-x keep-lines (and also M-x
flush-lines) in an *Occur* buffer and had it do the right thing.
Would it work to just have M-x occur call keep-lines when the buffer
it's used on is already an output buffer from an earlier M-x occur?
