If this means asking for help on an autoloaded function will load its
package, I don't think it should be the default.  We could perhaps
arrange for a button that would load the package and display the full
documentation, but that's all.

Again, displaying the source by default is too much, IMNSHO: the code
of a function could be very large.  Doing this by default also assumes
that the user will necessarily want to look at the source, something
that is IME questionable at best.  So this should also be optional,
and even then the code should be changed to avoid showing a huge
*Help* window (since currently, we fit the window size to the text in
the *Help* buffer).
