I need to leave soon, but here's my attempt to simplify the patch by
removing the nested `let's and placing the simple `if' alternatives
first. I haven't tested it or the original to be sure either works and
whether they're equivalent.
(if (not w3m-use-title-buffer-name)
(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*"))
(if (not (and tailbufs new-buffer-number))
(let ((n (1+ new-buffer-number)))
(dolist (buf (cdr tailbufs))
(w3m-buffer-set-number buf (setq n (1+ n))))
(format "%s<%d>" name (1+ new-buffer-number))))))))
