I think the commit is buggy. After evaluating the patched function, I
selected w3m buffer #12 out of 28 tabs open, and opened a link in a new
buffer. The new buffer name became "*w3m*<12><2>", and it causes the
original tab #12 to jump in the w3m-select-buffer pop-up to position 2.
It may have also corrupted some data structure somewhere because I'm now
having other problems with moving tabs. What I had before, which seemed
to be working for me was:

(defun w3m-generate-new-buffer (name &optional next)
  "Create and return a buffer with a name based on NAME.
Make the new buffer the next of the current buffer if NEXT is non-nil."
  (when next
    (let* ((tailbufs (let ((w3m-fb-mode nil))
		       (let ((all-w3m-buffers (w3m-list-buffers)))
			     (memq (current-buffer) all-w3m-buffers))))
	   (new-buffer-number (w3m-buffer-number (car tailbufs))))
      (when (string-match "\\*w3m\\*\\(<\\([0-9]+\\)>\\)?\\'" name)
	(setq name "*w3m*"))
      (when (and tailbufs new-buffer-number)
	(dolist (buf (reverse (cdr tailbufs)))
	  (w3m-buffer-set-number buf (1+ (w3m-buffer-number buf))))
	(setq name (format "%s<%d>" name (1+ new-buffer-number))))))
  (let ((prev (and (eq major-mode 'w3m-mode) (current-buffer)))
	(new (generate-new-buffer name)))
    (with-current-buffer new
      (w3m-mode)
      (setq w3m-previous-session-buffer prev))
    new))
