[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-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.
