Hi Al,

Thank you. This feels a bit like a "time machine", i.e. being
instantly transferred to the almost forgotten distant past for the joy
of seeing familiar faces. Well, past, present or future --- Al Viro is
always right (especially as far as filesystems' code is concerned) and
I safely defer to you --- if you say it is better, then it most
certainly is, dear friend. And to me it looks better too.

Kind regards,
Tigran
