Oops, I'm sorry, I made the test with the wrong file and thus gave the
wrong recipe.

Try this as a web.el:
;; some useful comments
(define-alternatives web)
;; End of file.

Notice that point is moved in front of (setq ...), and not
(define-alternatives ...) although that is where the defcustom happens.
This is because the mechanism searches for the following regexp :
"^([^ ]+\\(?:\\s-\\|
\\|;.*
\\)+['(]?web-alternatives\\_>"

(this happens in find-function-search-for-symbol).
