Multiple undo again...

If you want to do the redo you just do the update to tip on this parallel .hgbackup dir. And if you want you can move anywhere in the tree of changes in this .hgbackup dir.

But does this conveniently support multiple levels of undo? Of course, 
Mercurial naturally supports multiple level "undo/redo" by design: it's 
the desire to discard "undone" work that you're interested in, I 
believe. Browsing the Wiki, I see that what I described as "some kind of 
cloning plus replaying of unwanted changesets", where I think I actually 
meant "wanted changesets" since I was talking about discarding unwanted 
work at that point, it looks like 'hg strip' would be able to support 
such a thing.
