This allows you to easily record a submodule.<name>.branch option in
.gitmodules when you add a new submodule. With this patch,
$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>
reduces to
$ git submodule add -b <branch> <repository> [<path>]
This means that future calls to
$ git submodule update --remote ...
will get updates from the same branch that you used to initialize the
submodule, which is usually what you want.

If you remove a submodule, in order to keep the repository so that
"git checkout" to an older commit in the superproject history can
resurrect the submodule, the real repository will stay in $GIT_DIR
of the superproject. A later "git submodule add $path" to add a
different submodule at the same path will fail. Diagnose this case
a bit better, and if the user really wants to add an unrelated
submodule at the same path, give the "--name" option to give it a
place in $GIT_DIR of the superproject that does not conflict with
the original submodule.
* jl/submodule-add-by-name:
submodule add: Fail when .git/modules/<name> already exists unless forced
Teach "git submodule add" the --name option
When adding a new submodule it can happen that .git/modules/<name> already
contains a submodule repo, e.g. when a submodule is removed from the work
tree and another submodule is added at the same path. But then the work
tree of the submodule will be populated using the existing repository and
not the one the user provided, which results in an incorrect work tree. On
the other hand the user might reactivate a submodule removed earlier, then
reusing that .git directory is the Right Thing to do.
As git can't decide what is the case, error out and tell the user she
should use either use a different name for the submodule with the "--name"
option or can reuse the .git directory for the newly added submodule by
providing the --force option (which only makes sense when the upstream
matches, so the error message lists all remotes of .git/modules/<name>).
In one test in t7406 the --force option had to be added to "git submodule
add", as that test re-adds a formerly removed submodule.

"git submodule add" initializes the name of a submodule to its path. This
was ok as long as the .git directory lived inside the submodule's work
tree, but since 1.7.8 it is stored in the .git/modules/<name> directory of
the superproject, making the submodule name survive the removal of the
submodule's work tree. This leads to problems when the user tries to add a
different submodule at the same path - and thus the same name - later, as
that will happily try to restore the submodule from the old repository
instead of the one the user specified and will lead to a checkout of the
wrong repository.
Add the new "--name" option to let the user provide a name for the
submodule. This enables the user to solve this conflict without having to
remove .git/modules/<name> by hand (which is no viable solution as it
makes it impossible to checkout a commit that records the old submodule
and populate it, as that will still check out the new submodule for the
same reason).
To achieve that the submodule's name is added to the parameter list of
the module_clone() helper function. This makes it possible to remove the
call of module_name() there because both callers of module_clone() already
know the name and can provide it as argument number two.

"git submodule" command DWIMs the command line and assumes a
unspecified action word for 'status' action. This is a UI mistake
that leads to a confusing behaviour. A mistyped command name is
instead treated as a request for 'status' of the submodule with that
name, e.g.
$ git submodule show
error: pathspec 'show' did not match any file(s) known to git.
Did you forget to 'git add'?
Stop DWIMming an unknown or mistyped subcommand name as pathspec
given to unspelled "status" subcommand. "git submodule" without any
argument is still interpreted as "git submodule status", but its
value is questionable.
Adjust t7400 to match, and stop advertising the default subcommand
being 'status' which does not help much in practice, other than
promoting laziness and confusion.

Various subcommands of the "git submodule" command exited with 0
status even though the path given by the user did not exist.
The reason behind that was that they all pipe the output of
module_list into the while loop which then does the action on the
paths specified by the commandline. Since the exit code of the
command on the upstream side of the pipe is ignored by the shell,
the status code of "ls-files --error-unmatch" nor "module_list" was
not propagated.
In case ls-files returns with an error code, we write a special
string that is not possible in non error situations, and no other
output, so that the downstream can detect the error and die with an
error code.
The error message that there is an unmatched pathspec comes through
stderr directly from ls-files. So the user still gets a hint whats going
on.

A recently introduced test uses an absolute path. But when run on Windows
using the MSYS bash, such a path is mangled into a Windows style path when
it is passed to 'git config'. The subsequent 'test' then compares the
mangled path to the unmangled version and reports a failure.
A path beginning with two slashes denotes a network directory
(//server/share path) and is not mangled. Use that trick to side-step the
issue. Just in case that 'git submodule init' regresses in such a way that
it accesses the URL, use a path name that is unlikely to exist on POSIX
systems, and that cannot be a server name on Windows.

Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there. To make that work the git directory has
the core.worktree configuration set in its config file to point back to
the work tree.
That core.worktree is an absolute path set by the initial clone of the
submodule. A relative path is preferable here because it allows the
superproject to be moved around without invalidating that setting, so
compute and set that relative path after cloning or reactivating the
submodule.
This also fixes a bug when moving a submodule around inside the
superproject, as the current code forgot to update the setting to the new
submodule work tree location.
Enhance t7400 to ensure that future versions won't re-add absolute paths
by accident and that moving a superproject won't break submodules.

Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there. When the submodule git directory needs
to be cloned because it is not found in .git/modules/<name> the clone
command will write an absolute path into the gitfile. When no clone is
necessary the git directory will be reactivated by the git-submodule.sh
script by writing a relative path into the gitfile.
This is inconsistent, as the behavior depends on the submodule having been
cloned before into the .git/modules of the superproject. A relative path
is preferable here because it allows the superproject to be moved around
without invalidating the gitfile. We do that by always writing the
relative path into the gitfile, which overwrites the absolute path the
clone command may have written there.
This is only the first step to make superprojects movable again like they
were before the separate-git-dir approach was introduced. The second step
is to use a relative path in core.worktree too.
Enhance t7400 to ensure that future versions won't re-add absolute paths
by accident.
While at it also replace an if/else construct evaluating the presence
of the 'reference' option with a single line of bash code.

One of the tests in t7400 fails if the trash directory has a

$ mkdir /tmp/git-test
$ mkdir /tmp/git-test/real
$ ln -s real /tmp/git-test/link

$ ./t7400-submodule-basic --root=/tmp/git-test/link

not ok - 41 use superproject as upstream when path is relative and no url is set there
The failing test does:
git submodule add ../repo relative &&
...
git submodule sync relative &&
test "$(git config submodule.relative.url)" = "$submodurl/repo"
where $submodurl comes from the $TRASH_DIRECTORY the user
gave us. However, git will resolve symlinks when converting
the relative path into an absolute one, leading them to be
textually different (even though they point to the same
directory).

Change `git submodule add' to add the new submodule <path> with `git
add --force'.
I keep my /etc in .git with a .gitignore that contains just
"*". I.e. `git status' will ignore everything that isn't in the tree
already. When I do:
git submodule add <url> hlagh
git-submodule will get as far as checking out the remote repository
into hlagh, but it'll die right afterwards when it fails to add the
new path:
The following paths are ignored by one of your .gitignore files:
hlagh
Use -f if you really want to add them.
fatal: no files added
Failed to add submodule 'hlagh'
Currently there's no way to add a submodule in this situation other
than to remove the ignored path from the .gitignore while I'm at it.
That's silly, when you run `git submodule add' you're explicitly
saying that you want to add something *new* to the repository. Instead
it should just add the path with `git add --force'.
Initially I implemented this by adding new -f and --force options to
`git submodule add'. But if the --force option isn't supplied it'll
get as far as cloning `hlagh', but won't add it.
So the first thing the user has to do is to remove `hlagh' and then
try again with the --force option.
That sucks, it should just add the path to begin with. I can't think
of any usecase where you've gone through the trouble of typing out
`git submodule add ..', but wish to be overriden by a `gitignore'. The
submodule semantics should be more like `git init', not `git add'.
