Prefer list1 (X) to Fcons (X, Qnil) when building lists.
This makes the code easier to read and the executable a bit smaller.
Do not replace all calls to Fcons that happen to create lists,
just calls that are intended to create lists. For example, when
creating an alist that maps FOO to nil, use list1 (Fcons (FOO, Qnil))
rather than list1 (list1 (FOO)) or Fcons (Fcons (FOO, Qnil), Qnil).
Similarly for list2 through list5.
