From 489c6b7af54b6bdfecf46c055927d2452f709060 Mon Sep 17 00:00:00 2001

Subject: 1. Add the ability to tweak the token output before targets in job
 mode.    E.g.,  .MAKE.JOB.PREFIX=${.newline}---[${.MAKE.PID}]    would
 produce

   ---[1234] target ---

2. Added ${.newline} as a simple means of being able to include '\n' in the
   assignment of .MAKE.JOB.PREFIX

Obtained from:	NetBSD
