Dear list,

In a number of notes (recent and in the list archive) I have seen \resetsetups, used (always) as in a block of code like this from Gerben Wierde:

\startsetups chapter:before
  \page[left]
  \noheaderandfooterlines
  \startalignment[left,nothyphenated]
	\startnarrower[4*left]
	    \em \getbuffer[chapter:quote]
	\stopnarrower
  \stopalignment
  \resetsetups[quote:text]
  \page[right]
  \noheaderandfooterlines
  \blank[force,2*big]
\stopsetups

What is the purpose of \resetsetups in this code? I see no different result without it, and all I can determine from list and document searches is that this is a vestigal command from x-fo processing.
