It seems that diff can not do comparison on the decompressed files in
.gz and .bz2 files. I could first decompress the .gz and .bz2 file and
then do the comparison. But it would be convenient to be able to
directly compare without explicitly decompressing any files. Could
somebody add this feature to diff?
