From e0ef8495e98ae5ae796ec23bf438eef413557193 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Mon, 14 Jun 2010 00:32:09 -0500 Subject: [PATCH] revert: do not rebuild argv on heap Set options in struct rev_info directly so we can reuse the arguments collected from parse_options without modification. This is just a cleanup; no noticeable change is intended.
