The comment in varstr_cmp() claims that it returns -1, 0 or 1. That's
not accurate then.
Comment and test case fixed. I considered changing varstr_cmp to really
return -1, 0 or 1, but I didn't because the behavior has been unchanged
for ages and all the callers are happy with it. That's a heavily called
function so any extra cycles there could make a difference.
