There's a question on SO about splitting hunks using magit, and the two solutions given are to either stage the region (mark a region, hit stage), or to shrink/grow all hunks using `+` & `-`. That's not what I'm after.

In magit's status buffer, I want to split a hunk into two hunks, at the point, or at least at the lines around the point.

Turning this (excuse my bad diff formatting)

    @@ blah blah blah
    - foo
    + bar
    + baz
    +

Into

    @@ blah blah
    - foo
    + bar
    
    @ blah blah
    + baz

When the point is on bar.

Motivations include `baz` being a debug statement, so I'd like to drop it from the commit of `foo` & `bar` without getting rid of it. Or just `bar` and `baz` being only partially related, meaning that their changes should not be in the same commit.
