From: Phillip Wood <phillip.w...@dunelm.org.uk>
If HEAD has changed since the rebase stopped or rebase stopped due to
a failed exec then 'git rebase --continue --autostage' will autostage
changes that cannot be commited. Fix this by reordering some of the
checks so that 'git rebase --continue --autostage' never stages
changes unless they can be committed. Also reword some error
messages to account of --autostage and try and make them clearer.

This could do with some tests the check the correct error message is
given in each failure case. However I'm expecting to change the error
messages based on the feedback I get to this patch so I'll add the
tests once the messages are finalized. I've tried to give a bit more
explanation in the error messages as I found some of the previous
messages didn't explain why rebase couldn't continue. Splitting the
advice out means it is consistent between different code paths and
should make it easier to optionally disable it in future if anyone
wanted to add that. As for the formatting of the messages I wonder if
they would be better without so many empty lines (I find the current
messages a bit intimating as they seem so long). e.g.
If you wish to squash the unstaged changes into the last commit, run:
git add -u
git commit --amend \$gpg_sign_opt_quoted
If they are meant to go into a new commit, run:
git add -u

In both cases, once you're done, continue with:
