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
