Please correct me if I'm wrong, it is my understanding that one
cannot use a command-line switch to tell emacs to read a config
file *other* than the standard ~/.emacs.
You are only partly wrong: Emacs has a --load command-line switch that
would load any file you name. But such loading is not 100% equivalent
to how Emacs loads a .emacs file, because .emacs is read at a certain
point during the Emacs session startup, while files given via --load
are read at a different point. So the effects could be subtly
different, especially with respect to display setup.
That's good to know, thanks, but, again, I'm puzzled: why would
Emacs treat ~/.emacs differently from a user-specified alternative?
