This is actually the rigth thing to do. Rebasing is not wrong, if it is 
done judiciously (and not on already-exposed stuff).

Rebasing is bad if
 - you do it so late in the game that all test experience is basically 
   worthless
 - after you've pushed out and other people have seen and depend on that 
   branch (and you didn't warn them)
 - you do it to other peoples git commits, so that their tree (that was 
   the source of the commit) now has the same commit duplicated as 
   something else.

I wrote a posting about rebasing to Dave Airlie on dri-devel, that might 
be googleable. Hmm. Here:

so rebase isn't bad, it's often a great way to fix things as you go along. 
It just goes with a few basic caveats.
