"rev-parse --verify --quiet $name" is meant to quietly exit with a
non-zero status when $name is not a valid object name, but still
gave error messages in some cases.

  stash: prefer --quiet over shell redirection of the standard error stream
  refs: make rev-parse --quiet actually quiet

  grammofix in user-facing messages

Use `git rev-parse --verify --quiet` instead of redirecting
stderr to /dev/null.

Teach "git stash list -p" to show the difference between the base
commit version and the working tree version, which is in line with
what "git show" gives.

When you list stashes, you can provide arbitrary git-log
options to change the display. However, adding just "-p"
does nothing, because each stash is actually a merge commit.

This implementation detail is easy to forget, leading to
confused users who think "-p" is not working. We can make
this easier by defaulting to "--first-parent -m", which will
show the diff against the working tree. This omits the
index portion of the stash entirely, but it's simple and it
matches what "git stash show" provides.

People who are more clueful about stash's true form can use
"--cc" to override the "-m", and the "--first-parent" will
then do nothing. For diffs, it only affects non-combined
diffs, so "--cc" overrides it. And for the traversal, we are
walking the linear reflog anyway, so we do not even care
about the parents.
