Re: log --pretty/--oneline: ignore log.decorate

Yeah, I considered to further narrow it down to the --pretty=raw case;
because that is not something we do for the default --show-notes, I opted
for consistency.  But a decoration and notes are quite different, and
such a consistency perhaps is not worth it.  How about this on top?

Since I consider normal output, --pretty=raw, and --oneline to be the
only useful output formats for git-log, I think of the right behavior
as:

  - normal: show both by default, since that is the point of the
    features

  - raw: show neither, since we are probably parsed by a script

  - oneline: don't show notes, as they are inherently multi-line. Do
    show decorations, as they inherently fit the hash+subject model

User-formats are useful, too, but outside the scope, as they should
always show exactly what was requested, and nothing more.

For the other formats, I couldn't care less. So your patch is fine, but
I would also be fine with turning it back on _just_ for --oneline, and
leaving all other pretty formats with it disabled.

The patch itself looks fine. As you know, it needs to revert some of the
test updates from your previous tip.

We should also either apply on top or squash in:

-- >8 --
Subject: [PATCH] script with rev-list instead of log

Because log.decorate now shows decorations for --pretty=oneline,
we must explicitly turn it off when scripting. Otherwise,
users with log.decorate set will get cruft like:

  $ git stash
  Saved working directory and index state WIP on master:
    2c1f7f5 (HEAD, master) commit subject

Instead of adding --no-decorate to the log command line,
let's just use the rev-list plumbing interface instead,
which does the right thing.

git-submodule has a similar call. Since it just counts the
commit lines, nothing is broken, but let's switch it, too,
for the sake of consistency and cleanliness.
