Sorry I didn't notice until now, but `--source` makes me think it will behave like `hg rebase --source` and absorb from the given commit and all its descendants. I would have preferred `--from` (and maybe a `--into` for choosing which commits to absorb into in the future).

Maybe I'm also misunderstanding what this patch does in that case. `hg absorb -r A` will not obsolete A? I would think it definitely should do that. Perhaps the successors or the absorbed commit should be all the nodes absorbed into as well as any potential leftovers (which were not absorbed).

nit: I think I've heard that `^` needs to be quoted on Windows, so maybe `-s '.^+.'`
