Suppose that I use the macro in file `foo.el' to define function `fun'. If I then do C-h f fun, I see this in *Help*: fun is an interactive compiled Lisp function in `foo.el'. The library name foo.el is a link here. However, if I click the link, I get an error message: Cannot find definition of `fun' in library `foo.el' Fair enough; help can't know where the function definition is, though it is able to identify the file. Even if help can't take me to the right place in the source file, I think it should open the file - and provide the error message, inviting me to search for it in the file. This would be analogous to what we do when Emacs cannot find the source C file that defines a built-in - at least on Windows, it opens a file dialog box that lets you navigate to the source file. I think it's great that the source file is identified (correctly), and it's good that the file name is a link. However, if the definition cannot be located in the file, the file should be opened, and then a message can say that the definition can't be located.
