You've quoted selectively.  He also said "Unix-style 'touch'", from 
which one could quite legitimately infer he wants the other features of 
the Unix touch command, including the automatic creation of missing files.

Unless you know something more about the OP's needs than he's posted 
publicly, you're just guessing too... even if we both agree yours is the 
more likely interpretation.
