Yeah, it does things properly – via a linked list. So appends are
fast. At the end it converts the list into an array via:
            aval = hlinklist2array(list, 0);

which does things properly too. I'm not sure why I've had the
impression that (z) is somewhat slow, for a zshrc with 20001
characters it runs in:

( a=(${(z)buff}) ; )  0,00s user 0,00s system 83% cpu 0,005 total

which is a very good time. It was probably when I was optimizing
fast-syntax-highlighting and a time like 100 ms seemed large.
