i'm not enthusiastic about having to change nearly every file server.
status files will be seekable but most synthetic ones won't.
some synthetic files will never be seekable in tail's sense because
they have no end, but they do interpret offsets, so are they QTSEEK or not?
isn't tail's seek an optimisation to avoid reading the file to the end?
unseekable synthetic files typically are length 0 (because they have
no particular length), or tiny (pipes have a hack that stat shows what's in them)
so change the test to declare seekable only if the file is big enough
to warrant it. one hack deserves another. then we can get back
to trying to get a version of ghostscript that doesn't blow up on
recent pdf/ps.
