X-Git-Tag: v1.7.8-rc0~80^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=86a0a408b900eecc9d0d4a1eb8ae223181e96679;p=git.git

commit: factor out clear_commit_marks_for_object_array

Factor out the code to clear the commit marks for a whole struct
object_array from builtin/checkout.c into its own exported function
clear_commit_marks_for_object_array and use it in bisect and bundle
as well.  It handles tags and commits and ignores objects of any
other type.
