You are right of course. But my original complaint was about the fact
that ksh will fail with 4 byte keysyms. This bug affects rxvt and
unfortunatly the (my) console.

I have NetBSD/i386 1.6 for the record. Do other versions really give
BTW: I think I complained about wscons' keysyms here some time ago...
I still don't know why NetBSD actually does produce this syms like
^[[8~ for <END>. /etc/share/termcap suggests this is used only by
rxvt, wscons and some old xterm-v5 or so...

However you twist it, the fact that sh, ksh and bash share one
.profile causes trouble.
The only clean solution is IMHO a ksh specific rc file. And your code
only tries to emulate what is missing in ksh. Clever, maybe, but this
is most definitly an error in ksh (and bash too, see the other mail..).

Thanks. I'm a lot smarter in the morning. Really.
