When you use a feature name rather than a filename (i.e. a symbol rather
than a string) in eval-after-load, it evals as soon as the feature is
provided, not after the file is loaded. ffap.el contains
(provide 'ffap)
at the beginning of the file, so your expression gets evaluated before
ffap-alist has been initialized. It really should be at the end, since
the feature doesn't really exist until the whole file is loaded.
