Yuck. While double-checking some refactoring, I realized this test does
not actually generate the correct input!

It omits the "ref-prefix" header. _And_ it accidentally expands $_ in
the shell rather than in perl.
Hah, nice find. You'd think that one of us would have caught it earlier
given that we both discussed it.
Really, I'd have thought that ls-refs would complain about a totally
bogus capability. I'll see if I can fix that, as well.
