That patch addresses only the empty string, not other strings that 
cannot be converted (e.g., a string consisting of a single space). This 
turns out to be a longstanding bug in printf. I installed the attached 
fancier patch which should address the more-general problem, and which 
adds some test cases. I tested this on cfarm104.cfarm.net which is 
running macOS 12.6.
