Yeah, with "rebase -i", it is a part of end-user experience to see
these comments, and a check to make sure they are shown to guide the
user is certainly a good idea.

A test of "rebase" without "-i" is a different matter.  Maybe in the
future, while we still reuse the machinery used for the interactive
mode to implement the non-interactive rebase, we may tweak it so
that we do not generate commented lines, only to be skipped by the
parser, in the todo list file that is only used internally.

Thanks.
