From 0a02186f924aee1bd69f18ed01f645aa332ce0d1 Mon Sep 17 00:00:00 2001 From: Dustin Sallings Date: Sat, 10 May 2008 15:36:29 -0700 Subject: [PATCH] Allow tracking branches to set up rebase by default. Change cd67e4d4 introduced a new configuration parameter that told pull to automatically perform a rebase instead of a merge. This change provides a configuration option to enable this feature automatically when creating a new branch. If the variable branch.autosetuprebase applies for a branch that's being created, that branch will have branch..rebase set to true.
