Unfortunately, this is highly distribution-specific. On my FC4 system, for example, less will correctly view gzipped files, RPM packages and other file types, thanks to LESSOPEN. On the other hand, zless won't handle most of these, because it is itself just an application of the LESSOPEN facility. I suggest that this be tackled locally by each distribution, as it's rather hard for the completion code to figure out on the fly how less has been extended by the use of LESSOPEN.
