We cannot remove the _+_ trick, until old make is completely deprecated.
But we don't want to set it to + for bmake since it breaks make -N
which is used to supress the normal handling of targets marked with .MAKE
(which seems broken in fmake and might be why _+_ was introduced).
Add some comments to explain what's gong on.
