rebase: clear merge when aborting before any rebasing (issue4661)
The check of the inrebase function was not correct, and it failed to
consider the situation in which nothing has been rebased yet, *and*
the working dir had been updated away from the initial revision.
But this is easy to fix. Given the rebase state, we know exactly where
we should be standing: on the first unrebased commit. We check that
instead. I also took the liberty to rename the function, as "inrebase"
doesn't really describe the situation: we could still be in a rebase
state yet the user somehow forcibly updated to a different revision.
We also check that we're in a merge state, since an interrupted merge
is the only "safe" way to interrupt a rebase. If the rebase got
interrupted by power loss or whatever (so there's no merge state),
it's still safer to not blow away the working directory.
