Comment 5 for bug 89945

Hmm, strnvis isn't quite right. I guess this unreliable quoting (consider what happens if the filename contains a single quote!) is OK for something that is just for human consumption, though I'd still like something that actually corresponds to real shell quoting in future. I'll apply a variant of this for the meantime.

By the way, please don't change the Maintainer field when it already contains an address @ubuntu.com.
