Then why not use `M-n' directly, with every successive `M-n' inserting the
next symbol/URL/file name to the minibuffer?  I have a simple patch that
does this for the grep prompt, but it was held due to the feature freeze.
However, to implement a replacement for ffap, it should be improved further
to allow extending the list of default values with more user-defined values.
I.e. instead of giving the list of default values as an argument of one of
the minibuffer functions, there should be a new buffer-local variable with
a user-defined function to get some text from the buffer and add it to
the list of default values.
