Oh good, I have an excuse to stick to 24.5.1 for a while longer then.

I was curious. The default is t since the variable's introduction [1].
Interestingly the thread/bug that resulted in that commit started with
"report this bug to git" [2]. Something about git-stash. I quote the
original mail here in case anyone wants to look into it (not sure if
it's actually reported here before, I don't pay much attention to
git-stash mails)

Bad news, everyone!

When a stash contains changes for several files, and "stash pop"
encounters conflicts only in some of them, the rest of the files are
stages automatically.

At least, that happens with Git 2.1.0 on my machine, and some
commenters here: http://stackoverflow.com/a/1237337/615245

So then when we unstage the files which had conflicts after resolving
those, the result is mixed. Which doesn't look right.

What shall we do? Unstage the automatically-staged files? Revert the
changes from this bug? It seems Git really wants the changes staged
after the conflict resolution.
