From: Junio C Hamano Date: Mon, 9 Jul 2007 07:51:23 +0000 (-0700) Subject: rebase: allow starting from a dirty tree. X-Git-Tag: v1.5.4-rc0~209^2~3 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=6c9ad166dbbf9e5a0c09450b892151dbec49b8dc;p=git.git rebase: allow starting from a dirty tree. This uses the new "git stash create" interface to stash away the dirty state you have in your working tree before starting a rebase, and then replaying it when you are done with stashing.
