Okay, I'll check this printnode() out...

    Zefram> 	opts[CHASELINKS] = 1;

Well, there's a reason to my madness ;-)...

I simply don't like directly editing some data structures that might
or might not transmogrify into something completely different...

On the other hand, you're right in your (implied) statement that
dosetopt might carry too much overhead...

So, if TPTB gives me the ok to use your suggestion (that is,
they/he/she/it guarantees opts to stay a simple int[]), I will.

Thanks. I'd really love to see a couple more comments on this
beast. Especially on fns like 'xsymlink'... I had to RTFS to find out
I had to free(3) the result... and had to guess (more or less) on
zsfree (the doc on the mem-mgt could be better... or maybe I could be
smarter ;-)
