I can't answer that, but I can tell that when I manually delete the last
lines of text and whitespace in such a buffer (saying "find finished
..."), it works as expected (though I'm getting a message saying that "1
rename actions failed").  But I'm definitely able to change permissions
with wdired then.  So it seems possible to make the feature work, the
infloop results from the unsuitable termination condition of the loop in
`wdired-preprocess-perms'.

Michael.
