Unit deletions should not always be trivial differences in DiffMerge

In a base aware (3 way) comparison, DiffMerge will always treat a deletion of an element as a trivial merge. A setting should be provided so that, when enabled, all deletions (or moves) are treated as conflicts that must be resolved manually.

    The Diff&Merge will soon go thru major improvements.
    This is just one of the aspects, but we are looking at a bunch of use cases around it, which will subsume this one.

    Thanks!

    That's a very useful observation - thank you.

    I think this is a bug, not an enhancement. Also, I disagree with your proposed solution: rather then providing a user setting to treat all deletions as conflicts - which we will all have to enable in order to avoid the bug - the solution should be to correct the DiffMerge algorithm so it correctly identifies the conflict in situations like your example, while still treating deletions as trivial changes when safe to do so.
