From 11932954e0122c115be23862aabfacb565a4cbed Mon Sep 17 00:00:00 2001
From: rcyeske <rcyeske>
Date: Fri, 2 Mar 2001 05:25:02 +0000
Subject: * actions.c (cmd_source): Open the file.  Error report as
 appropriate.

* main.c (read_rc_file): Take a file pointer rather than a
filename.
(read_startup_files): If ~/.ratpoisonrc is not readable try
/etc/ratpoisonrc.

* actions.c: Use PRINT_DEBUG instead of fprintf.  Put useful error
text in calls to message().
(cmd_select): Show the window list if there is no such window
number.
