SYNOPSIS and usage say [NAME=value] while multiple assigments are fine:
$ make -p FOO=1 BAR=2 | grep -e^FOO -e^BAR
BAR = 2
FOO = 1
I'm sure ports(7) wouldn't work if only one was accepted, hence it suprises
me that none of the BSDs document it with triple dots, like targets.
Am I missing some detail here or is this just a very old oversight?
