Again, thats  becaue you put it in the wrong place - you didn't put it into
the extensino, but into another package that urxvt knows nothing about and
will not call anything in.

BNote that tab_osc_seq_perl is also not called, until you tell the
extension to forward on_osc_seq_perl to it, so urxvt certainly calls
on_osc_seq_perl - nothing else would.

No, you need to implement both tab_osc_seq_perl AND on_osc_seq_perl for this
to work. urxvt calls the latter, your code then forwards this to
tab_osc_seq_perl.

The problem is that tab_osc_seq_perl is wrong, as this event shouldn't be
handled by every tab, only by the main tabbed window. It's not a big deal,
but either you do it right, or somehow clean it up afterwards.

It works fine also in tabbedex, believe me. Just remove the forwarder you
added from on_osc_seq_perl to tab_osc_seq_perl and you will see it's no
longer called. That's because on_osc_seq_perl is called, not
tab_osc_seq_perl.

Just callinng "->new_tab (qw(-e /bin/zsh))" or so should work.
