Subject: Stash away the original head in ORIG_HEAD when resetting.
X-Git-Tag: v0.99.4~3^2~5
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=32173e69881a35e4e7a53be3ba80091ae9fa8f35;p=git.git

Stash away the original head in ORIG_HEAD when resetting.

When rewinding the head, stash away the value of the original
HEAD in ORIG_HEAD, just like git-resolve-script does.
