| Actually, you can argue that this is a bug in poptParseArgvString. It's
| being passed a string of "" and not handling it graciously by setting
| argc to 0. But it's easy enough to work around here. I think the patch
| below is probably the right thing to do.

Thanks, merged.  (And I wrote a test case so it should be clearer what's
going on if we ever have a similar bug.)
