Subject: Make play show no last command when there hasn't been one
X-Git-Tag: v4.3.29~51
X-Git-Url: http://git.pond.sub.org/?p=empserver;a=commitdiff_plain;h=354664eef28d8bc98b9cdcd2932033849bd385e9

Make play show no last command when there hasn't been one

Before, it printed NULL, which isn't helpful.
