Subject: Split up git-pull-script into separate "fetch" and "merge" phases.
X-Git-Tag: v0.99~503
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=7ef76925d9c19ef74874e1735e2436e56d0c4897;p=git.git

Split up git-pull-script into separate "fetch" and "merge" phases.

This allows you to just fetch stuff first, inspect it, and then
resolve the merge separately if everything looks good.
