I'm still getting this weird behaviour in 25.1, but the above doesn't
work exactly for me.

Set dabbrev-eliminate-newlines to "t".

Type:

one  tt
one  ww

Then in the next line I have to type:

one 
   ^- space

and M-/ (dabbrev-expand) completes it to:

one ww

Then if I hit M-/ again, point jumps up to the line above and replaces
"ww". Subsequent M-/'s continue to fiddle with the same line.
