And this is an issue today for jumping to the definitions of functions in C files, since those are not packaged with Emacs. Today, that is broken out of the box if source-directory is still around. So if you think this behavior is bad, then should we fix it to not happen for the case of C files? Perhaps by clearing source-directory when Emacs is installed, so that Emacs cannot find obsolete C files out of the Git repository?
