sound great.

(a meant 1.13.25 in the above paragraph btw)

if tar hasn't been upgraded, this should matter, but maybe the options
hdup gives to tar are different.

strange, looks like tar expects a different kind of archive (either
sparse are non-sparse).
You could play with hdup.h.in:

#define SPARSE                " --sparse "

redfine that to "", recompile and test. If that doesn't change
anything, I don't know what's wrong.

funny, these are underflows in the 'dot' calculation for the overview
message (how many dots to print).

I will keep this in mind for 2.0.5.

what does plain tar say about those archives?
