[egit-dev] Rebase usability

[Robin Rosenberg <robin.rosenberg@xxxxxxxxxx>]

First, It's marvelous to see rebase in EGit. Rebase has been one of the main reasons
to use the command line extensively.

On usability, I wonder wheter doing like C Git does is the right thing. I'd expect
the selected version should be included in the rebase for several reasons. I know
C Git does not. In the command this is easily fixes, just do "git rebase -i commit^". 

In Egit that's not as easy, especially if you start with a filtered history, where
it's not as easy to select the previous commit. In a complex graphh it is not easy
even when no filtering takes place.

In most cases including the selected commit in the edit list would cause no issues since
picking the first commits in the original order is a noop, but if the selected commit is
a merge, the effect would be a surprise.
