rememberedSocket data corrupted when +/- buttons clicked

[dabbler0]

if a
  fd 10
else
  fd 20

Select the "20" in fd 20
Click the "+" button so it becomes

if a
  fd 10
else if ``
  fd 20
else
  ``

Now the rememberedSocket location for fd 20 is corrupted, because the if is a new extra token. Any drags will throw errors.
