FWIW, I very much like what I see in 

   $ git checkout hn/git-checkout-m-with-stash && git diff @{1}

output.  It is great that we do not have to do any dry-run, because
the "real" run safely aborts, we can do the "stash && merge && unstash"
dance as a fallback instead.  All the credit goes to Phillip and you
for the idea and the execution of this.

I do use "checkout -m" a few times a week, but I do not do anything
complex with submodules or run the command with unrelated local
modifications, so there may be changes in behaviour I haven't seen
in corner cases that I do not exercise.
