#6 xdelta may fail for corrupt gzips

[Ben Escoto]

It appears that if xdelta is used to compare corrupt
gzip files, it will try to uncompress them, and then
will fail if the uncompression fails. For instance,
here is a "screenshot":

$ xdelta delta ../temp/wml-2.0.6.tar.gz
wml-2.0.6.tar.gz out
xdelta: gzread wml-2.0.6.tar.gz failed: Success
$

Ungzipping stuff may work best in many situations, but
it seems that xdelta should be correct in all cases.
At any rate, using xdelta on a corrupt gzip doesn't
seem that weird a situation to me. This is for version
1.1.1; maybe it is fixed already.

Thanks Ben, for submitting this report. This should be easy to fix...

The thing that concerns me the most about this is the
"failed: Success" output. I have fixed that. You can use
the -p (--pristine) option to disable automatic GZIP file
recognition, otherwise.
