I see I am quoted in one of them as "it's a little weird for add -p to
change the working tree", but I want to make clear that I _don't_ oppose
a feature like this. I think it would be super useful. We may find a way
to avoid that "weird" property (e.g., by putting the "combined"
stash/add mode under a different command's "-p"), or we may just accept
it.
I guess our messages crossed ;-) I do agree that it would be very
nice to have a feature like this.
