short followup on vpath/VPATH stuff

[Robert P. J. Day]

  sorry for being so confused about this, but i may be misunderstanding 
the fundamental design of VPATH and how it relates to *targets*.

  section 4.5 strongly suggests that VPATH is for prereqs only: "The 
directory search features of make facilitate this by searching several 
directories automatically to find a *prerequisite*."  [emphasis mine]

  but the very next page reads, "however, VPATH specifies a search list
that make applies for all files, including files which are *targets* of
rules." [again, emphasis mine]

  this can certainly be clearer, methinks.  or, i could just be smarter.
