Subject: [PATCH] pull: introduce a pull.rebase option to enable --rebase

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Sat, 5 Nov 2011 15:35:58 +0000

Currently we either need to set branch.<name>.rebase for existing
branches if we'd like "git pull" to mean "git pull --rebase", or have
the forethought of setting "branch.autosetuprebase" before we create
the branch.

But there's no way to globally configure "git pull" to mean "git pull
--rebase" for existing branches, introduce a "pull.rebase" option to
do that.

This option will be considered at a lower priority than
branch.<name>.rebase, i.e. we could set pull.rebase=true and
branch.<name>.rebase=false and the latter configuration option would
win.
