(To make the advice to `w3m-view-this-url-1' work, evaluating
 the `w3m-view-this-url' Lisp source is needed since
 `w3m-view-this-url-1' is an inline function.)

Anyway I found no problem in implementing that feature.  How about
making the arg passed to `recenter' customizable?  For example:

(defcustom w3m-view-this-url-and-recenter 1
  "Integer used to recenter the name link visited (passed to `recenter').
Nil means don't perform `recenter'."
  :group 'w3m
  :type '(radio (const :format "%t " nil) integer))

[...]
  (when w3m-view-this-url-and-recenter
    (recenter w3m-view-this-url-and-recenter))
[...]
