A lot of shell scripts contained stuff starting with
while case "$#" in 0) break ;; esac
and similar. I consider breaking out of the condition instead of the
body od the loop ugly, and the implied "true" value of the
non-matching case is not really obvious to humans at first glance. It
happens not to be obvious to some BSD shells, either, but that's
because they are not POSIX-compliant. In most cases, this has been
replaced by a straight condition using "test". "case" has the
advantage of being faster than "test" on vintage shells where "test"
is not a builtin. Since none of them is likely to run the git
scripts, anyway, the added readability should be worth the change.
A few loops have had their termination condition expressed
differently.

When we are fetching from a repository that is on a local
filesystem, first check if we have all the objects that we are
going to fetch available locally, by not just checking the tips
of what we are fetching, but with a full reachability analysis
to our existing refs. In such a case, we do not have to run
git-fetch-pack which would send many needless objects. This is
especially true when the other repository is an alternate of the
current repository (e.g. perhaps the repository was created by
running "git clone -l -s" from there).
The useless objects transferred used to be discarded when they
were expanded by git-unpack-objects called from git-fetch-pack,
but recent git-fetch-pack prefers to keep the data it receives
from the other end without exploding them into loose objects,
resulting in a pack full of duplicated data when fetching from
your own alternate.
This also uses fetch--tool pick-rref on dumb transport side to
remove a shell loop to do the same.

Please see http://bugs.debian.org/409887
http-fetch expected the URL given at the command line to have a trailing
slash anyway, and then added '/objects...' when requesting objects files
from the http server.
Now it doesn't require the trailing slash in <url> anymore, and strips
trailing slashes if given nonetheless.

This patch adds support for a dummy remote '.' to avoid having
to declare a fake remote like
[remote "local"]
url = .
fetch = refs/heads/*:refs/heads/*
Such a builtin remote simplifies the operation of "git-fetch",
which will populate FETCH_HEAD but will not pretend that two
repositories are in use, will not create a thin pack, and will
not perform any useless remapping of names. The speed
improvement is around 20%, and it should improve more if
"git-fetch" is converted to a builtin.
To this end, git-parse-remote is grown with a new kind of
remote, 'builtin'. In git-fetch.sh, we treat the builtin remote
specially in that it needs no pack/store operations. In fact,
doing git-fetch on a builtin remote will simply populate
FETCH_HEAD appropriately.
The patch also improves of the --track/--no-track support,
extending it so that branch.<name>.remote items referring '.'
can be created. Finally, it fixes a typo in git-checkout.sh.

Some workflows require use of repositories on machines that cannot be
connected, preventing use of git-fetch / git-push to transport objects and
references between the repositories.
git-bundle provides an alternate transport mechanism, effectively allowing
git-fetch and git-pull to operate using sneakernet transport. `git-bundle
create` allows the user to create a bundle containing one or more branches
or tags, but with specified basis assumed to exist on the target
repository. At the receiving end, git-bundle acts like git-fetch-pack,
allowing the user to invoke git-fetch or git-pull using the bundle file as
the URL. git-fetch and git-ls-remote determine they have a bundle URL by
checking that the URL points to a file, but are otherwise unchanged in
operation with bundles.
The original patch was done by Mark Levedahl <mdl123@verizon.net>.
It was updated to make git-bundle a builtin, and get rid of the tar
format: now, the first line is supposed to say "# v2 git bundle", the next
lines either contain a prerequisite ("-" followed by the hash of the
needed commit), or a ref (the hash of a commit, followed by the name of
the ref), and finally the pack. As a result, the bundle argument can be
"-" now.

With a configuration entry like this:

url = git://repo.or.cz/alt.git/git/
fetch = +refs/heads/*:refs/remotes/alt-git/*
tagopt = --no-tags
you do not have to say "git pull --no-tags alt-git". Just
saying "git pull alt-git" would suffice.
Obviously, if you want to get the tag from such an alternate
remote in a separate namespace, you could also do something like:
[remote "alt-git"]
url = git://repo.or.cz/alt.git/git/

Recent commit ae1dffcb28 by Junio
changed the way --upload-pack was passed around between clone,
fetch and ls-remote and modified the handling of the command

Unfortunately FreeBSD 6.1 insists that the expression
expr --upload-pack=git-upload-pack : '-[^=]*=\(.*\)'
is illegal, as the --upload-pack option is not supported by their
implementation of expr.
Elsewhere in Git we use z as a leading prefix of both arguments,
ensuring the -- isn't seen by expr.

Sometimes, people have only fetch access into a bare repository
that is used as a back-up location (or a distribution point) but
does not have a push access for networking reasons, e.g. one end
being behind a firewall, and updating the "current branch" in
such a case is perfectly fine.
This allows such a fetch without --update-head-ok, which is a
flag that should never be used by end users otherwise.

Junio rightly pointed out that the --reflog-action parameter
was starting to get out of control, as most porcelain code

not the lower-level actions it invoked.
At Junio's suggestion we are introducing the new set_reflog_action
function to all shell scripts, allowing them to declare early on
what their default reflog name should be, but this setting only
takes effect if the caller has not already set the GIT_REFLOG_ACTION
environment variable.
