Subject: revision.c: add show_object_with_name() helper function
X-Git-Tag: v1.7.8-rc0~57^2~5
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=91f175165aba17903ab928da543052ea335fc924;p=git.git

revision.c: add show_object_with_name() helper function

There are two copies of traverse_commit_list callback that show the object
name followed by pathname the object was found, to produce output similar
to "rev-list --objects".

Unify them.
