Doesn't change a thing.  The commit message is part of the commit
identity (the sha1).  The problem of rebase/--amend/etc is that it
creates a new commit "sideways", without any link to the original
version.  So when someone with the original version does a git pull
the system does not know to substitute the new commit instead and go
from there.  In short "rebases are not tracked", so you can't update
your tree automatically when rebases happened.

  OG.
