What does this do when Emacs is invoked with "--chdir DIR"?

No, it's too late to change the semantics of invocation-directory, it
has been with us in its present meaning far too long. If you look at
how it's generated, you will understand: it starts with the value of
argv[0], there are fallbacks for when that doesn't include leading
directories (one of the fallbacks is to search PATH, for example).
Once again, Emacs knows its original current directory when it starts,
so exposing that to Lisp should be easy, if that is desired.
