Nguyễn Thái Ngọc Duy 4dcb167fc3 fetch: add --unshallow for turning shallow repo into complete one
The user can do --depth=2147483647 (*) for restoring complete repo
now. But it's hard to remember. Any other numbers larger than the
longest commit chain in the repository would also do, but some
guessing may be involved. Make easy-to-remember --unshallow an alias
for --depth=2147483647.

Make upload-pack recognize this special number as infinite depth. The
effect is essentially the same as before, except that upload-pack is
more efficient because it does not have to traverse to the bottom
anymore.

The chance of a user actually wanting exactly 2147483647 commits
depth, not infinite, on a repository with a history that long, is
probably too small to consider. The client can learn to add or
subtract one commit to avoid the special treatment when that actually
happens.

(*) This is the largest positive number a 32-bit signed integer can
    contain. JGit and older C Git store depth as "int" so both are OK
    with this number. Dulwich does not support shallow clone.

git-fetch-pack(1)
=================
NAME
----
git-fetch-pack - Receive missing objects from another repository
SYNOPSIS
--------
[verse]
'git fetch-pack' [--all] [--quiet|-q] [--keep|-k] [--thin] [--include-tag]
[--upload-pack=<git-upload-pack>]
[--depth=<n>] [--no-progress]
[-v] [<host>:]<directory> [<refs>...]
DESCRIPTION
-----------
Usually you would want to use 'git fetch', which is a
higher level wrapper of this command, instead.
Invokes 'git-upload-pack' on a possibly remote repository
and asks it to send objects missing from this repository, to
update the named heads. The list of commits available locally
is found out by scanning the local refs/ hierarchy and sent to
'git-upload-pack' running on the other end.
This command degenerates to download everything to complete the
asked refs from the remote side when the local side does not
have a common ancestor commit.
OPTIONS
-------
--all::
Fetch all remote refs.
--stdin::
Take the list of refs from stdin, one per line. If there
are refs specified on the command line in addition to this
option, then the refs from stdin are processed after those
on the command line.
+
If '--stateless-rpc' is specified together with this option then
the list of refs must be in packet format (pkt-line). Each ref must
be in a separate packet, and the list must end with a flush packet.
-q::
--quiet::
Pass '-q' flag to 'git unpack-objects'; this makes the
cloning process less verbose.
-k::
--keep::
Do not invoke 'git unpack-objects' on received data, but
create a single packfile out of it instead, and store it
in the object database. If provided twice then the pack is
locked against repacking.
--thin::
Fetch a "thin" pack, which records objects in deltified form based
on objects not included in the pack to reduce network traffic.
--include-tag::
If the remote side supports it, annotated tags objects will
be downloaded on the same connection as the other objects if
the object the tag references is downloaded. The caller must
otherwise determine the tags this option made available.
--upload-pack=<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).
--exec=<git-upload-pack>::
Same as \--upload-pack=<git-upload-pack>.
--depth=<n>::
Limit fetching to ancestor-chains not longer than n.
'git-upload-pack' treats the special depth 2147483647 as
infinite even if there is an ancestor-chain that long.
--no-progress::
Do not show the progress.
-v::
Run verbosely.
<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.
<refs>...::
The remote heads to update from. This is relative to
$GIT_DIR (e.g. "HEAD", "refs/heads/master"). When
unspecified, update from all heads the remote side has.
