Indeed, it's to make the compiler aware of the function. I followed the example of notmuch-show.el (defvar w3m-current-buffer, line 391), but it sounds like declare-function is a better way to accomplish this. I haven't written a whole lot of emacs lisp, so thanks for the tip. Given David's comments about requiring w3m instead it might be moot, but if not I'll make this change for the next version.
