after rebase, hg [g]log shows obsolete changesets

[Ernie Rael]

Bug?

Moving to new system, found old scripts, wanted to test Splice merge set 
up. Ran the old scripts and in one, after /hg rebase -b 2 -d tip/ I see 
obsolete changesets in hg log/glog. I thought they were hidden by 
default, needed /--hidden/ to see them. The /hg prune/ documentation 
seems to indicate that.
