[PATCH] clone-pack and clone-script: documentation and add a missing parameter.

While adding the documentation for these two commands, I noticed
that the name of the program on the other end (git-upload-pack)
is already almost configurable but git-clone-pack lacked command
line parameter parsing to actually use anything but default, so
I introduced --exec= like other remote commands while I was at it.

+git-clone-pack(1)
+=================
+v0.1, July 2005
+
+NAME
+----
+git-clone-pack - Clones a repository by receiving packed objects.
+
+
+SYNOPSIS
+--------
+'git-clone-pack' [-q] [--exec=<git-upload-pack>] [<host>:]<directory> [<heads>...]
+
+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 invoking 'git-unpack-objects' locally
+to receive the pack.
+
+OPTIONS
+-------
+-q::
+	Pass '-q' flag to 'git-unpack-objects'; this makes the
+	cloning process less verbose.
+
+--exec=<git-upload-pack>::
+	Use this to specify the path to 'git-upload-pack' on the
+	remote side, if is not found on your $PATH.
+	Installations of sshd ignores 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>:]<directory::
+	The (possibly remote) repository to clone from.
+
+<heads>...::
+	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.

Documentation/git-clone-script.txt

+git-clone-script(1)
+===================
+v0.1, July 2005
+
+NAME
+----
+git-clone-script - Clones a repository.
+
+
+SYNOPSIS
+--------
+'git clone' [-l] [-u <upload-pack>] [-q] <repository> <directory>
+
+DESCRIPTION
+-----------
+Clones a repository into a newly created directory.
+
+OPTIONS
+-------
+-l::
+	When the repository to clone from is on a local machine,
+	this flag bypasses normal "git aware" transport
+	mechanism and clones the repository by making a copy of
+	HEAD and everything under objects and refs directories.
+	The files under .git/objects/ directory are hardlinked
+	to save space when possible.
+
+-q::
+	Operate quietly.  This flag is passed to "rsync" and
+	"git-clone-pack" commands when given.
+
+-u <upload-pack>::
+	When given, and the repository to clone from is handled
+	by 'git-clone-pack', '--exec=<upload-pack>' is passed to
+	the command to specify non-default path for the command
+	run on the other end.
+
+<repository>::
+	The (possibly remote) repository to clone from.  It can
+	be an "rsync://host/dir" URL, an "http://host/dir" URL,
+	or [<host>:]/dir notation that is used by 'git-clone-pack'.
+	Currently http transport is not supported.
+
+<directory>::
+	The name of a new directory to be cloned into.  It is an
+	error to specify an existing directory.
