gitweb: supply '-n' to gzip for identical output
For projects that do not release official archives, gitweb's snapshot
feature would be an excellent alternative, and but without the '-n'
('--no-name') argument, gzip includes a timestamp in output which results
in different files. Because some systems hash/checksum downloaded files
to ensure integrity of the tarball (e.g FreeBSD), it is desirable to
produce tarballs in a reproducible way for that purpose.
Whilst '--no-name' is more descriptive, the long version of the flag is
not supported on all systems. In particular, OpenBSD does not appear to
support it.
Supply '-n' to gzip to exclude timestamp from output and produce idential
output every time.
