Subject: When logging warning messages, there are now three scenarios: o If a
 prompt is executing the command, only display the warning to   that prompt o
 If a prompt is executing a ``load'' command, display the warning   to all
 prompts *and* syslog o Otherwise, display the warning to all prompts *and*
 syslog.
