tar-1.13.25

[David Ronis]

Hi, 

I'm trying to write an script that uses tar to create multiple-volume
backup files of a large disk.  I also need to control their length
(I'm going to burn them onto CD's later). I ran into trouble with the
1.13 released version in specifying --tape-length=700000 generated an
error.  This seems to be fixed in the alpha source I'm using.  However,
now it complains about using --gzip with --multi-volume; I'm pretty
sure that this wasn't the behavior in the past.  It seems that you are
simply spawning the compression off to gzip, couldn't it be handled
internally?  It makes a big difference in the number of CD's I'll have
to use, unfortunately not in a way that I can predict reliably.

One other feature request/query.  Ideally, what I expect to have is a
series of backup-files, foo.tgz.1, foo.tgz.2, ...  each approximately
filling a single CD.  Is there some way the extension can be
incremented automatically for multi-volume CD's? (I can do this with
the --info-script option, but it might be nicer to have tar do it all
by itself).
