[PATCH 0/2] git-pull: Allow --stat and --no-stat to be used with --rebase

[Tor Arne Vestbø]

These two small patches teach git-rebase to understand --stat, and git-pull
to forward --stat to git-rebase when used with --rebase. Comments welcome!

Tor Arne Vestbø (2):
  git-rebase: Add --stat and --no-stat for producing diffstat on rebase
  git-pull: Allow --stat and --no-stat to be used with --rebase

[PATCH 1/2] git-rebase: Add --stat and --no-stat for producing diffstat on rebase

[Tor Arne Vestbø]

The behavior of --verbose is unchanged, but uses a different state
variable internally, so that the meaning of verbose output may be
expanded without affecting the diffstat. This is also reflected in
the documentation.

The configuration option rebase.stat works the same was as merg.stat,
but the default is currently false.

Thanks Jakub, I knew there was a reason that git-config.txt was so empty ;)

And sorry for the double post, --cc to git-send-email seems to override
what's in the config, not compliment it.
