If the vetted function supplies zero arguments, previously you would
get an error message like this:
Printf format %v reads arg #1, but call has only 0 args
"has only 0 args" is an odd construction, and "has 0 args" sounds
better. Getting rid of "only" in all cases simplifies the code and
reads just as well.
