Hi

Recently i stumbled upon an old stash entry. It was clear to me that the
stash only contained non-indexed worktree changes. So i assumed to get
insight by doing

    $ git log -1 -p stash@{0}

But surprisingly the result was "no patch" (The problem which i was not
aware at that time was the fact that a stash commit is a merge). So i asked
a question on stackoverflow (1) an learned that there are different default
options used depending on the git command used:

    $ git show stash@{0}
    $ git diff stash@{0}^..stash@{0}

work with default, but for git-log i need to 

    $ git log -1 -p --cc stash@{0}

to make it behave the same. This does not seem reasonable to me, though i
read about commit 1aec791 (2) in git's own repository. What do you think?

Maybe - as a compromise - just show any kind of hint instead of nothing?

Best regards
Henning

Junio did some slight tweaks to --cc and -p,
see 82dee4160cc6d1b0d792c9f07b5803cd42abc610/
and its parent. That should be live in the upcoming 2.8.
