Things you didn't know about C, #7212:

There is no sane way to get sscanf to tell you how many characters
were consumed, if you want to allow a variable number of arguments.

The special format %n is patently useless for this, because you
have to insert it at every conceiveable point in the string and
that presumes full explicit whitespace markup.

Parse -w argument "by hand", to catch illegal input like "1,INF,15"
