Subject: Safely log when a command error cannot be sent
X-Git-Tag: 0.0.1~9
X-Git-Url: https://mudpy.org/gitweb?a=commitdiff_plain;h=f6f7c26e115c61153017b50660d0561f854a8e20;p=mudpy.git

Safely log when a command error cannot be sent

If a command triggers an error back to the user and sending that
error raises an exception, log it and continue to avoid crashing the
engine.
