Parameter "-c" ignored if it last (gzip incompatible)

[ktrace]

In original gzip

gzip -c -d foo.tar.gz > bar.tar

and

gzip -d foo.tar.gz -c > bar.tar

work identical: keep foo.tar.gz unchanged, create bar.tar as uncompressed .tar

pigz -c -d foo.tar.gz > bar.tar

work as needed

pigz -d foo.tar.gz -c > bar.tar

ignore "-c", bar.tar empty foo.tar.gz became foo.tar

see ib/xarchiver#40

pigz is working as documented, where options are processed on the command line in order with the file names. Options affect files to the right of the options, and options and operations can be changed and reversed as they are processed left to right.

It's obviously incompatible with any other single file compressor then.
