An assumption I agree with:
Use git-stash when you want to record the current state of the working
directory and the index, but want to go back to a clean working
directory. The command saves your local modifications away and reverts
the working directory to match the HEAD commit.

Note the "saves your local modifications", which is, to me, the same
as "please do remember this until I tell you to forget it".

I agree fully with what Wincent is saying, stashes have an explicit
way of cleaning them up:
    Remove all the stashed states. Note that those states will then be
subject to pruning, and may be difficult or impossible to recover.
To me this suggests that otherwise stashes will _not_ be subject to
pruning, which is exactly what this patch does, it makes sure that
stashes are not subject to pruning unless you 'git stash clear' first.
