Re: [BUG] - git rebase -i performs rebase when it shouldn't?

[Eugene Sajine <euguess@gmail.com>]

I got your point about the HEAD which is by default get's added to the
end of the command, so it becomes

git rebase --onto master topic HEAD

I will think about it it more.

I'm pretty sure that i was surprised by the fact that i've got
different behavior in interactive and non-interactive variants, but i
will recheck.

I forgot to mention it was in windows version of git.
I will try to provide the printout of my actions tomorrow when i will
get to this machine.

Thanks a lot,
Eugene
