Terry, AFAIK gzip can have additional bits added since it is a collection of "members" which have a header and trailer which are sequentially processed. This is in stark contrast to other compression/archive utilities which often have a "directory" or file listing at the beginning and so you cannot mess (easily) with the file. Concatenating gz files should result in a valid file.
