That's not as easy as you'd think.  `read-file-name':

If DEFAULT-FILENAME is omitted or
nil, then if INITIAL is non-nil, the default is DIR combined with
INITIAL; otherwise, if the current buffer is visiting a file,
that file serves as the default; otherwise, the default is simply
the string inserted into the minibuffer.

Like, WTF.

Hm...  perhaps if I bind buffer-file-name...  Yup, that work.  Fixed on
the trunk now.
