Re: "git stash pop" is doing an unwanted "git add" when there are conflicts.

I don't think that's a good idea. Git always marks conflicts in the
index for other operations. Besides being inconsistent with the rest of
git, it drops useful information that other tools can use. For example,
one cannot "git checkout --conflict=diff3" afterwards, or use "git
mergetool" to kick off a third-party merge tool.

Not to mention that the information is lost to the user themselves. If
we touched 10 files and 2 had conflicts, there is now no way for the
user to ask "where were the conflicts?". They can either find the stash
output in their terminal scrollback, or grep for things that look like
conflict markers.
