+pppd: Do not clobber exit codes on hangup
+
+When a modem hangup occurs, pppd unconditionally sets the exit status code
+to EXIT_HANGUP. This patch only sets EXIT_HANGUP if the exit status code is
+not already set to an error value.
+
+The motiviation of this patch is to allow applications which remote control
+pppd to react properly on errors, e.g. only redial (relaunch pppd) if there
+was a hangup, but not if the CHAP authentication failed.
