I learned about it from the documentation for print:

  -l  Print the arguments separated by newlines instead of spa-
      ces.  Note: if the list of arguments is empty,  print  -l
      will  still  output  one  empty  line.  To print a possi-
      bly-empty list of arguments one per line, use print  -C1,
      as in `print -rC1 -- "$list[@]"'.

I don't think I ever wrote or saw code where -l is correct and -C1 is wrong.
