Hmm. For some reason it seems to have broken the quoted item at the
single quote. Notice the curtailed string it claims to be expanding.

AARRGGHH!! It's a bug. Gosh, I wonder why nobody noticed that one

Below is a very hacky patch (untested) that might fix it. No time to do
a proper job ... I'm off for the weekend.
