    revert: option to choose what to keep, not what to discard · c1d83d916e85

    I know the you (the reader) are probably tired of discussing how `hg
    revert -i -r .` should behave and so am I. And I know I'm one of the
    people who argued that showing the diff from the working copy to the
    parent was confusing. I think it is less confusing now that we show
    the diff from the parent to the working copy, but I still find it
    confusing. I think showing the diff of hunks to keep might make it
    easier to understand. So that's what this patch provides an option
    One argument doing it this way is that most people seem to find `hg
    split` natural. I suspect that is because it shows the forward diff
    (from parent commit to the commit) and asks you what to put in the
    first commit. I think the new "keep" mode for revert (this patch)
    matches that.
    In "keep" mode, all the changes are still selected by default. That
    means that `hg revert -i` followed by 'A' (keep all) (or 'c' in
    curses) will be different from `hg revert -a`. That's mostly because
    that was simplest. It can also be argued that it's safest. But it can
    also be argued that it should be consistent with `hg revert -a`.
    Note that in this mode, you can edit the hunks and it will do what you
    expect (e.g. add new lines to your file if you added a new lines when
    editing). The test case shows that that works.
