Retire git-clone-pack 

The program is not used by git-clone since git-fetch-pack was extended
to allow its caller do what git-clone-pack alone did, and git-clone was
updated to use it.

git-clone-pack(1)
=================
NAME
----
git-clone-pack - Clones a repository by receiving packed objects
SYNOPSIS
--------
'git-clone-pack' [--exec=<git-upload-pack>] [<host>:]<directory> [<head>...]
DESCRIPTION
-----------
Clones a repository into the current repository by invoking
'git-upload-pack', possibly on the remote host via ssh, in
the named repository, and stores the sent pack in the local
repository.
OPTIONS
-------
--exec=<git-upload-pack>::
Use this to specify the path to 'git-upload-pack' on the
remote side, if it is not found on your $PATH.
Installations of sshd ignore the user's environment
setup scripts for login shells (e.g. .bash_profile) and
your privately installed git may not be found on the system
default $PATH. Another workaround suggested is to set
up your $PATH in ".bashrc", but this flag is for people
who do not want to pay the overhead for non-interactive
shells by having a lean .bashrc file (they set most of
the things up in .bash_profile).
<host>::
A remote host that houses the repository. When this
part is specified, 'git-upload-pack' is invoked via
ssh.
<directory>::
The repository to sync from.
<head>...::
The heads to update. This is relative to $GIT_DIR
(e.g. "HEAD", "refs/heads/master"). When unspecified,
all heads are updated to match the remote repository.
+
Usually all the refs from existing repository are stored
under the same name in the new repository. Giving explicit
<head> arguments instead writes the object names and refs to
the standard output, just like get-fetch-pack does.
