As per Tuesday's meeting RTFM:
ibm.com gave me the first hint: If no command template appears on the command line, xargs uses echo by default.
Which then let me find it in Linux's man page: ... and executes the command (default is /bin/echo) ...
So they were basically using xargs as a newline-eater to combine all the lines of the iteration into one.
