Errr. Oops.
Sorry everyone - the patch does not really work. I keep testing it with
a *file* passed on mkuzip's stdin, all the while feeling surprised that
lseek() works on the pipe... when there is no pipe at all :(
I just tested it with a real pipe, and of course, it failed. Again,
sorry for wasting your time; I guess it'd be best if I tucked in for
the holidays now :(
G'luck,
Peter
