(wdired-change-to-wdired-mode, wdired-finish-edit)

(wdired-search-and-rename): Simplify code.
(wdired-preprocess-files, wdired-preprocess-perms): Make
read-only property of preceding character rear-nonsticky to
avoid that it can be modified.  Put old-name and old-link
properties on character preceding name and replace
put-text-property by add-text-properties.
(wdired-get-filename, wdired-get-previous-link): Get old-name
and old-link properties from character preceding name and
simplify code.
(wdired-preprocess-perms, wdired-set-bit, wdired-toggle-bit)
(wdired-perms-to-number): Make local-map property
rear-nonsticky to avoid that text following permissions may be
modified.  Use add-text-properties instead of put-text-property
when changing a permission bit.
(wdired-change-to-dired-mode): Remove stickiness properties.
