IIRC `wdired' is full of such niceties.  Here the problem is that
`dired-move-to-filename' moves to the start of the old filename,
skipping the prepended string.  Maybe it's sufficient to remove that
call as in the patch below since the subsequent

(search-forward (wdired-get-filename t) nil t)

should move to the right position anyway.  If not, we'll have to rewrite
this function from scratch.
