Thanks, I've pushed your changes to the master branch.  If as result
you no longer think of Emacs as being silly, we all win.

[Message part 3 (message/rfc822, inline)]

The autoload generation code inserts a form with a string that may or
may not have text properties, depending on if the buffer is already
open.

(if (fboundp 'register-definition-prefixes)
             (register-definition-prefixes "foo"
                                           '(#("foo-" 0 4 (fontified nil)))))

(if (fboundp 'register-definition-prefixes)
             (register-definition-prefixes "foo" '("foo-")))

This makes autoload generation depend on the odd condition of whether
the file under consideration is already open and fontified.
