[BUG] Null EMACSPACKAGEPATH causes an error

Tuesday, 12 May 1998

        $ env EMACSPACKAGEPATH= ./xemacs -no-site-file -no-init-file -f kill-emacs
^GWrong type argument: stringp, nil

The environment variable EMACSPACKAGEPATH doesn't seem to be documented.
There doesn't seem to be an equivalent command-line flag to set it, either.
