Subject: [PATCH] Remove upload-tar and make git-tar-tree a thin wrapper to
git-archive
The command now issues a big deprecation warning message and runs
git-archive command with appropriate arguments.
git-tar-tree $tree_ish $base always forces $base to be the leading
directory name, so the --prefix parameter passed internally to
git-archive is a slash appended to it, i.e. "--prefix=$base/".

When <base> is specified it is added as a leading path to the files in the
generated tar archive.

-SYNOPSIS
---------
-'git-upload-tar' <directory>

-DESCRIPTION
------------
-Invoked by 'git-tar-tree --remote' and sends a generated tar archive
-to the other end over the git protocol.
-
-This command is usually not invoked directly by the end user.
-The UI for the protocol is on the 'git-tar-tree' side, and the
-program pair is meant to be used to get a tar archive from a
-remote repository.
-
-
-OPTIONS
--------
-<directory>::
- The repository to get a tar archive from.
