I didn't consider your second alternative, but I still think the first
is better or at least equivalent.  Counting the keystrokes of the
first alternative they are:
  1. press $
  2. move right
  3. enter formula
  4. press $
For the second:
  1. press $ twice, but the second pressure will insert only one dollar sign
  2. enter formula
  3. press $
  4. move right
Thus, I'm inclined to keep `TeX-math-close-double-dollar'.  That said,
I've a reason to suspect there are really few AUCTeX users writing
regularly in plain TeX, if I'm right not many people will worry about
all this :-)

I'm submitting the (hopefully) definitive patch.  If there are no
objections I'll install it.

Bye,
Mosè
