Without the '-n' ('--no-name') argument, gzip includes timestamp in
output which results in different files. Important systems like FreeBSD
ports and perhaps many others hash/checksum downloaded files to ensure
integrity. For projects that do not release official archives, gitweb's
snapshot feature would be an excellent stand-in but for the fact that the
files it produces are not identical.
Supply '-n' to gzip to exclude timestamp from output and produce idential
output every time.
