Re: Suggestion for C-h f, describe-function

[Richard Stallman]

    The problem is with stuff compiled in another machine or another
    directory: if some user has an installed Emacs and uses the C source
    code link, the worst that can happen is that he gets landed in a
    nonsensical place instead of no place at all, since there is no C
    source code in the installed Emacs tree.

Yes.  That's why I suggest trying source-directory first.
If the file exists there, that is probably the right file.
If not, it can look for the installed Lisp file.

Thanks for bringing it up.

    Another possibility would be to have an option that would embed the
    source tree info into files that are byte-compiled.

I do not understand the idea.

    level module interface, but it would be nice if one could set one's
    Emacs up at least manually to have it know just where to find the
    source trees of stuff.

It sounds like you mean having a list instead of source-directory.
I guess we could.
