This commit extends the todo epilogue to include the usage text that is
shown during a standard git rebase.
The specific content of this can vary between Git versions, though only
slightly. The main change I can see looking at
https://github.com/git/git/blame/master/git-rebase--interactive.sh is
that a "drop" command was added 2.6.0 onwards, so two epilogue files are
supplied to deal with this. Further ones could be added in the future.

Use pbr to update AUTHORS by running:
python setup.py build_sphinx
However prevent it from updating the ChangeLog as its current formatting
is less desirable.
