From 64736f55e159ae981a7331e9b3fbd178d84c2655 Mon Sep 17 00:00:00 2001
From: Paul Eggert <eggert@twinsun.com>
Date: Sun, 30 Apr 1995 15:34:52 +0000
Subject: [PATCH] (datearg): If rlog options are specified explicitly, omit the
 implicit '-d>DATE' option. (repository, rlog): Allow absolute paths to CVS
 repositories. Look only at the first line of CVS/Repository.
