Jacob has already mentioned git-new-workdir from Git contrib, but
there are other ways to do the same or almost the same....
First of all, you can always copy your directory and thus creating
another clone. It is very simple and straightforward solution, but
it takes extra space due an extra copy of the repository. Usually,
it is not a big issue in practice, because your working tree tends
to be larger than the repository itself...
However, if you want to save disk space, you can use local clone. When
you clone your (like: git clone old_dir new_dir), git tries to use hard
links if it is possible. So, it may save disk space. However, if you
repack your original repo then a new pack will be created, and saving
from using the hard link will be lost. To prevent that from happening,
you can tell to the garbage collector to keep the main existing pack by
create a file that has the same name as the pack file plus the .keep
suffix:
touch .git/objects/pack-<SHA-1>.keep
then all changes will be put into a separate pack.
There is one more way to save disk space is to use git clone --shared.
It does not require hard links, but it has some caveats. If you want to
use it, then read the documentation carefully and make sure you understand
all implications.
Actually, in most use cases, there is no reason to have more than one
working tree. Git is designed to work well with plenty branches and one
working tree. So, switching between two branches and recompiling a few
changed files is much faster then going to another directory and try to
work there, because when you go to another directory, you may hit cold
cache and disk is *slow*... Another thing is that you can do a lot of
things without checking out some branch. You can grep any revision in
your repository, you can insect any file from it, etc and you do not
have to checkout this revision in your working tree.

The first delta is a missing blank line between requests. I probably
can work around that with some sort of sed hackery and its likely
caused by a different libcurl version.
The second delta is libcurl sending *two* Accept headers to the
server. The first was set by the library as "*/*", but the second
was set by git-remote-curl. Here your libcurl is just plain *wrong*.
The application has said "I only support one content type, this one"
and the library still went and told the server "I accept anything
you have, just give it to me!".
I'm not sure what to do about this breakage in curl. We may have
to relax how we use HTTP since at least one version of libcurl
can't get this minor detail right.

Hmmph. Your libcurl also included the POST body in the verbose
message.

This only changes the behavior of "git check-ref-format -h"
without any other options and arguments.
This change cannot be breaking backward compatibility, since any
valid refname must contain a /. Most existing scripts use
arguments such as "heads/$foo". If some script checks the
refname "-h" alone, git check-ref-format will still exit with
nonzero status, and the only detrimental side-effect will be a
usage string sent to stderr.

* [PATCH/RFC 06/24] Show usage string for 'git show-ref -h'
From: Jonathan Nieder @ 2009-11-09 15:04 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git
In-Reply-To: <20091109150235.GA23871@progeny.tock>
This only changes the behavior of "git show-ref -h" without any
other options and arguments.
"show-ref -h" currently is short for "show-ref --head", which
shows all the refs/* and HEAD, as opposed to "show-ref" that
shows all the refs/* and not HEAD.
Does anybody use "show-ref -h"? It was in Linus's original, most
likely only because "it might be handy", not because "the command
should not show the HEAD by default for such and such reasons".
So I think it is okay if "show-ref -h" (but not "show-ref
--head") gives help and exits.
If a current script uses "git show-ref -h" without any other
arguments, it would have to be adapted by changing "-h" to
"--head".

* [PATCH 03/24] Show usage string for 'git cherry -h'
From: Jonathan Nieder @ 2009-11-09 15:04 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git
In-Reply-To: <20091109150235.GA23871@progeny.tock>
Treat an "-h" option as a request for help, rather than an
"Unknown commit -h" error.
"cherry -h" could be asking to compare histories that leads to
our HEAD and a commit that can be named as "-h". Strictly
speaking, that may be a valid refname, but the user would have to
say something like "tags/-h" to name such a pathological ref
already, so it is not such a big deal.
The "-h" option keeps its meaning even if preceded by other
options or followed by other arguments. This keeps the
command-line syntax closer to what parse_options would give and
supports shell aliases like 'alias cherry="git cherry -v"' a
little better.

Delay search for a git directory until option parsing has finished.
None of the functions used in option parsing look for or read any
files other than stdin, so this is safe.

"unpack-file -h" could be asking to save the contents of a blob
named "-h". Strictly speaking, such a pathological ref name is
possible, but the user would have to had said something like
"tags/-h" to name such a pathological ref already. When used in
scripts, unpack-file is typically not passed a user-supplied tag
name directly.

This change is strictly about 'git merge-ours -h' without
any other options and arguments.
This change cannot break compatibility since merge drivers are
always passed '--', among other arguments.
Any usage string for this command is a lie, since it ignored its
arguments until now. Still, it makes sense to let the user know
the expected usage when asked.

Treat an "-h" option as a request for help, rather than a "Not a
valid object name" error.
"commit-tree -h" could be asking to create a new commit from a
treeish named "-h". Strictly speaking, such a pathological ref
name is possible, but the user would have to had said something
like "tags/-h" to name such a pathological already. commit-tree
is usually used in scripts with raw object ids, anyway.
For consistency, the "-h" option uses its new meaning even if
followed by other arguments.
