From 32962c9bd5149005b163dff230670872eb99286a Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 8 Mar 2010 22:58:09 -0800 Subject: [PATCH] revision: introduce setup_revision_opt So far the last parameter to setup_revisions() was to specify the default ref when the command line did not give any (typically "HEAD"). This changes it to take a pointer to a structure so that we can add other information without touching too many codepaths in later patches. There is no functionality change.
