IMNSO this is not just annoying, but plain dangerous, because mis-use of
rebasing may end up removing your local changes (or remote changes).
Now that we promote the concept of feature branches, I hope we can
revert this.

Also, I have no doubt that some of us will start using feature branches
to share development with others, and if my understanding is correct
(which it may not be) rebasing locally and pushing to the remote feature
branch when it's not fastforward would screw up the other person's
branch state...  Or is my understanding not correct?

OK...  Thanks for pointing this out.

Either way, I hope someone who is a git expert can outline the correct
way of merging from master into a feature branch.  I still don't
understand what exactly 'rebase' does (I do only know it vaguely) in the
context of git (especially when pushing to remote), so I may end up
rebasing again when I shouldn't be.
