I haven't looked exactly why, but it looks like this patch can cause a regression; I tried using the NoOptDefVal on a flag (--pull), and it now failed when the flag before it is a boolean;
docker run -it --rm --pull=never alpine
invalid argument "--pull=never" for "--rm" flag: strconv.ParseBool: parsing "--pull=never": invalid syntaxMaybe because boolean flags have an implicit NoOptDefVal ?

Actually; same happens without that option set on the --pull flag, and I see the same for other flags;
docker run -it --rm --label foo=bar alpine
invalid argument "--label" for "--rm" flag: strconv.ParseBool: parsing "--label": invalid syntax
