[BUG] Invalid rebase command leaves unclean status

Hello git list

A bug in rebase -i: A typo in the command (for example in the branch name) still makes later invocations of rebase think a rebase is already in process.

I found this bug in master, and it was already reported to the mailing list under version 1.5.3.5, but there were no follow-ups to that mail. I'm using 1.5.3.7 and it is still present, and looking at the maint branch it does not seem to be mentioned in post-x.3.7 changes there. So I am now reporting this bug again. I'm sorry for not checking this in master, I'll have to ask someone on the list to do that.

# A sample session: # Invoking rebase with a typo, there is no "muster" branch $ git rebase -i muster fatal: Needed a single revision Invalid base $ git rebase -i master Interactive rebase already started $ git rebase --abort fatal: Needed a single revision # Even though rebase --abort reports an error, rebase's internal state is now cleared
