This is an apparent bug in xdelta.  Either the delta generation or the
delta application seems to be corrupting the data.

I tried this with both xdelta 0.20 and xdelta 0.22.  On the "xdelta
delta" command I tried both ">delta2" and "delta2" as a way of
specifying the destination.  I tried it with other data files and in
that case it seemed to work.

[kingdon@matlovich foo]$ ls -l

[kingdon@matlovich foo]$ xdelta delta showchar2.bmp gz.tst >delta2
[kingdon@matlovich foo]$ xdelta describe delta2
