Your original point appeared to be [...] it would be better to set $, to a newline.

I don't know how you get "it would be better to set $, to a newline" from "It's more flexible." My point was the opposite, that you didn't have to set it to a newline.

In the typical case ($, and $\ not used), eliminating the for eliminates a useless loop is eliminated.

In the atypical case ($, and $\ used), eliminating the for allows the Field Seperator ($,) to be used as the field sperator. Before removing the for, the Line Seperator ($\) was used as both the Line Seperator and the Field Seperator.

Update: Made the point even easier to read.
