I'm confused.  *How* does --rebase-merge mode help?  You're saying
"hey, if we use this, it solves the issue" but I don't see how to
pound this nail with that screwdriver.

I don't see how creating a branching history helps, and I don't see how to 
use the reset/label/merge commands to do anything but create a branching 
history.

I suppose it is possible to use the "reset" command in isolation
to describe the jump to a new base.  So you could have a history of:

# Command already executed:
# reset base
# pick A
# pick B
# pick C
# label rebase-1  User asked for a nested rebase
# reset A'

# Commands pending:
pick B'
pick C'
# rebase-2 complete, resume rebase-1
pick D
pick E

Is that what you were getting at?

I was thinking of it being implicit, but it might be nice for the initial
"reset" in each rebase to be explicit, *and not yet executed during
the initial todo edit*.

That makes it really clear that deleting the todo list entirely
results in no change to the tree.
