GIT 0.99.9d
This is primarily to include the 'git clone -l' (without -s) fix,
first spotted and diagnosed by Linus and caused James Bottomley's
repository to become unreadable. It also contains documentation
updates happened on the "master" branch since 0.99.9c

+DISCUSSION
+----------
+
+The list of <file> given to the command is fed to `git-ls-files`
+command to list files that are not registerd in the index and
+are not ignored/excluded by `$GIT_DIR/info/exclude` file or
+`.gitignore` file in each directory. This means two things:
+
+. You can put the name of a directory on the command line, and
+ the command will add all files in it and its subdirectories;
+
+. Giving the name of a file that is already in index does not
+ run `git-update-index` on that path.
+
+
+EXAMPLES
+--------
+git-add Documentation/\\*.txt::
+
+ Adds all `\*.txt` files that are not in the index under
+ `Documentation` directory and its subdirectories.
++
+Note that the asterisk `\*` is quoted from the shell in this
+example; this lets the command to include the files from
+subdirectories of `Documentation/` directory.
+
+git-add git-*.sh::
+
+ Adds all git-*.sh scripts that are not in the index.
+ Because this example lets shell expand the asterisk
+ (i.e. you are listing the files explicitly), it does not
+ add `subdir/git-foo.sh` to the index.

+MERGE STRATEGIES
+----------------
+
+resolve::
+ This can only resolve two heads (i.e. the current branch
+ and another branch you pulled from) using 3-way merge
+ algorithm. It tries to carefully detect criss-cross
+ merge ambiguities and is considered generally safe and
+ fast. This is the default merge strategy when pulling
+ one branch.
+
+recursive::
+ This can only resolve two heads using 3-way merge
+ algorithm. When there are more than one common
+ ancestors that can be used for 3-way merge, it creates a
+ merged tree of the common ancestores and uses that as
+ the reference tree for the 3-way merge. This has been
+ reported to result in fewer merge conflicts without
+ causing mis-merges by tests done on actual merge commits
+ taken from Linux 2.6 kernel development history.
+ Additionally this can detect and handle merges involving
+ renames.
+
+octopus::
+ This resolves more than two-head case, but refuses to do
+ complex merge that needs manual resolution. It is
+ primarily meant to be used for bundling topic branch
+ heads together. This is the default merge strategy when
+ pulling more than one branch.
+
+ours::
+ This resolves any number of heads, but the result of the
+ merge is always the current branch head. It is meant to
+ be used to supersede old development history of side
+ branches.
+
+
+EXAMPLES
+--------
+
+git pull, git pull origin::
+ Fetch the default head from the repository you cloned
+ from and merge it into your current branch.
+
+git pull -s ours . obsolete::
+ Merge local branch `obsolete` into the current branch,
+ using `ours` merge strategy.
+
+git pull . fixes enhancements::
+ Bundle local branch `fixes` and `enhancements` on top of
+ the current branch, making an Octopus merge.
+
+git pull --no-commit . maint::
+ Merge local branch `maint` into the current branch, but
+ do not make a commit automatically. This can be used
+ when you want to include further changes to the merge,
+ or want to write your own merge commit message.
++
+You should refrain from abusing this option to sneak substantial
+changes into a merge commit. Small fixups like bumping
+release/version name would be acceptable.
+
+Command line pull of multiple branches from one repository::
++
+------------------------------------------------
+$ cat .git/remotes/origin
+URL: git://git.kernel.org/pub/scm/git/git.git
+Pull: master:origin
+
+$ git checkout master
+$ git fetch origin master:origin +pu:pu maint:maint
+$ git pull . origin
+------------------------------------------------
++
+Here, a typical `$GIT_DIR/remotes/origin` file from a
+`git-clone` operation is used in combination with
+command line options to `git-fetch` to first update
+multiple branches of the local repository and then
+to merge the remote `origin` branch into the local
+`master` branch. The local `pu` branch is updated
+even if it does not result in a fast forward update.
+Here, the pull can obtain its objects from the local
+repository using `.`, as the previous `git-fetch` is
+known to have already obtained and made available
+all the necessary objects.
+
+
+Pull of multiple branches from one repository using `$GIT_DIR/remotes` file::
++
+------------------------------------------------
+$ cat .git/remotes/origin
+URL: git://git.kernel.org/pub/scm/git/git.git
+Pull: master:origin
+Pull: +pu:pu
+Pull: maint:maint
+
+$ git checkout master
+$ git pull origin
+------------------------------------------------
++
+Here, a typical `$GIT_DIR/remotes/origin` file from a
+`git-clone` operation has been hand-modified to include
+the branch-mapping of additional remote and local
+heads directly. A single `git-pull` operation while
+in the `master` branch will fetch multiple heads and
+merge the remote `origin` head into the current,
+local `master` branch.

+[NOTE]
+If the remote branch from which you want to pull is
+modified in non-linear ways such as being rewound and
+rebased frequently, then a pull will attempt a merge with
+an older version of itself, likely conflict, and fail.
+It is under these conditions that you would want to use
+the `+` sign to indicate non-fast-forward updates will
+be needed. There is currently no easy way to determine
+or declare that a branch will be made available in a
+repository with this behavior; the pulling user simply
+must know this is the expected usage pattern for a branch.
++
+[NOTE]
+You never do your own development on branches that appear
+on the right hand side of a <refspec> colon on `Pull:` lines;
+they are to be updated by `git-fetch`. The corollary is that
+a local branch should be introduced and named on a <refspec>
+right-hand-side if you intend to do development derived from
+that branch.
+This leads to the common `Pull: master:origin` mapping of a
+remote `master` branch to a local `origin` branch, which
+is then merged to a local development branch, again typically
+named `master`.
++
+[NOTE]
+There is a difference between listing multiple <refspec>
+directly on `git-pull` command line and having multiple
+`Pull:` <refspec> lines for a <repository> and running
+`git-pull` command without any explicit <refspec> parameters.
+<refspec> listed explicitly on the command line are always
+merged into the current branch after fetching. In other words,
+if you list more than one remote refs, you would be making
+an Octopus. While `git-pull` run without any explicit <refspec>
+parameter takes default <refspec>s from `Pull:` lines, it
+merges only the first <refspec> found into the current branch,
+after fetching all the remote refs. This is because making an
+Octopus from remote refs is rarely done, while keeping track
+of multiple remote heads in one-go by fetching more than one
+is often useful.

Some short-cut notations are also supported.

* A parameter <ref> without a colon is equivalent to
- <ref>: when pulling/fetching, and <ref>:<ref> when

pushing. That is, do not store it locally if
fetching, and update the same name if pushing.
