Good point.  And especially for net transfers a compressed format like
ZIP or TGZ (not yet implemented) would be better.

Would it make sense to have just one multiplexer command?  I.e.
something like this:

  git-archive -f <format> [extra]                <tree-ish> [<base>]
  git-archive -f <format> [extra] --upload       <tree-ish> [<base>]
  git-archive -f <format> [extra] --remote=<url> <tree-ish> [<base>]

[extra] stands for format specific options like the compression ratio
for ZIP.  The protocol spoken by upload and --remote would need to be
extended to be able to specify the format and any format specific options.

While we're discussing the command line interface, would it make sense
to support path specs, like e.g. ls-tree does?  Like this:

  git-archive -f <format> [extra] [--prefix=<base>] <tree-ish> [<path>]

Personally, I don't see the need for path specs for archive creation,
but IF we want to introduce them then the best time to do it would be
now, at the same time as introducing git-archive (or git-archive-tree).
