INIT file searching

[RLB at MIT-MC (Richard L. Bryan)]

According to the description in LISP RECENT, if I want to start a Lisp
with FOO's init file, I need to type :LISP FOO;FOO LISP (i.e., nodefault).
Suppose the search went like:

	B) JCL of the form:
		foo;	look for foo;<xuname> LISP, if not found try
				 foo;* LISP, if not found try
				 foo;foo LISP
		fn1	look for <sname>;fn1 >
		fn1 fn2 look for <sname>;fn1 fn2
		foo;fn1 look for foo;fn1 >
