a_colour_mux(): HORRIBLE FIX! Assign correct pointer (Χάρης Καραχριστιανίδης)..
The conditional pointer may either be some user string,
or a_COLOUR_TAG_IS_SPECIAL(). In both cases the "length"
may end up 0 (always in latter case), but we simply assign
the pointer to storage, storing a later invalidated pointer
instead of NIL in !IS_SPECIAL() cases!
This means that
colour 256 sum-thread fg=172 ''
will later crash (in at least optimized builds).
Luckily
colour 256 sum-thread fg=172
does not.
