I often put work away for later, then other stuff comes along, and a few weeks later, I want to inspect the stash, and find out what changes it would make if I applied it to working tree in its current state.
I know I can do a git diff on the stash, but this shows me all the differences between the working tree and the stash, whereas I'm just interested to know what the stash apply is going to change.
How can I do this?
