strip: move bookmarks to nearest ancestor rather than '.' If you've got this graph: 0-1-2 \ 3 and 3 is checked out, 2 is bookmarked with "broken", and you do "hg strip 2", the bookmark will move to 3, not 1. That's always struck me as a bug. This change makes bookmarks move to the tipmost ancestor of the stripped set rather than the currently-checked-out revision, which is what I always expected should happen.
