[OE-core] is there an actual defensible usage for combining "_append" and "+="?

[Robert P. J. Day]

  i've grumbled about this before -- the *apparent* redundancy in
combining the "_append" and "+=" constructs -- but someone recently
suggested there's a use case for that that weirds me out if true.

  given that "_append" defers appending, and that "+=" inserts a
space, the argument was that combining them both defers appending
*and* inserts a space when appending is finally done.

  *blink*.

   seriously? is that what that combination is being used for?

p.s. i don't even want to think what happens if you combine "_append"
and, say, "=+". or some other operator.
