> During startup, when Emacs reads `.../Emacs.app/Contents/Resources/site-lisp/subdirs.el` in a version of Emacs Trunk built on August 22, 2015, the value of the `default-directory` at the top of that file is:
> 
> "."

I think that is already too late.  Emacs determines its current
directory early on during startup, and then propagates that value to
every buffer it creates henceforth.

OK, but you can still add fprintf lines to init_buffer and rebuild
Emacs to tell us the value returned by get_current_dir_name when it
starts, right?
