   |  Which bmake fourtunately doesn't adhere to. I doubt you want
   |  	foo= bar	# see section 47.11
   |  to assign trailing whitespace to foo.
 
 Yet gmake and smake both do include it.
 
 On the other hand while with
 
 foo=
 foo += data       #comment
 
 all:
 	printf '<%s>\n' "$(foo)"
 
 gmake (like bmake) inserts a leading space from the += smake
 doesn't.
