From 4bee27ae43e6aa07aa0069ae39cb1c8a2b2cfcfd Mon Sep 17 00:00:00 2001
From: Jim Meyering <jim@meyering.net>

Subject: (main): Upon processing a bad --exclude-from or --max-depth option
 argument, don't exit right away, in case there are others. Rather record the
 failure and exit after processing other options.
