lexical #3/3, collapse append(NULL) into cp_ccom()
the sequence
orig_wlist = wlist;
append(NULL);
cp_ccom(wlist, ...);
is transformed.
expressions to care about in cp_ccom()
C1 := (wlist->wl_next != NULL)
C2 := (wlist->wl_word != NULL)
C3 := wl_length(wlist)
D1 := (orig_wlist != NULL)
D2 := (orig_wlist->wl_word != NULL)
D3 := wl_length(orig_wlist);
cases and their significance in cp_ccom():
orig_wlist = NULL;
wlist = wl_cons(NULL, NULL);
C1 == false
D1 == false
C2,C3 dont care
orig_wlist = wl_cons(E1, wl_cons(E2, ... wl_cons(En, NULL)))
wlist = wl_cons(E1, wl_cons(E2, .... wl_cons(En, wl_cons(NULL, NULL))))
C1 == true
D1 == true
C2 === D2
C3 === D3 + 1

lexical #9/19, aproach the `append'
cw has never been NULL here,
because we used to survive an update of cw->wl_next here
wlist hasn't been NULL either,
because there is no place where wlist becomes NULL without
setting cw to NULL as well. yet cw isn't NULL (see above)

lexical #3/19, attach and instantly remove a NULL wl_word here
this modification is faithful iff cw != NULL and cw->wl_next == NULL
cw != NULL because we have just survived an update of cw->wl_word
cw->wl_next == NULL is witnessed by:
1) cw either NULL or pointing to a wl_cons(,NULL)
2) cw not being modified, and no wl_next being modified
3) check of all function invocations with wlist/cw argument
not to modify any wl_next slot
which are:
1) cp_ccom(wlist, ...)
2) wl_free() always followed by goto nloop, which does a cw = wl_cons(,NULL)
and cp_ccom() doesn't modify any wl_next slot
the first part of the patch is intentionally similar to newword
`i' and `buf' can be modified here, because we will inevitably `goto done'
attach and instantly remove a NULL wl_word here
