Hi Gab. Please take a look at this minimal change to fix a security bugaboo. I
also fixed a string conversion call. Although I think this function would be
well served to use a CommandLine rather than a string, that's a bigger change
than I care to make right now in case a merge is requested. Thanks.

lgtm, but I agree that this code should use CommandLine instead.
