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"
