"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.

  Revert "completion: fix shell expansion of items"

The codepath for handling "--tee" ends up relaunching the test
script under a shell, and that one has to be a Bourne.  But we
incorrectly used $SHELL, which could be a non-Bourne (e.g. zsh or
csh); we have the Makefile variable $SHELL_PATH for exactly that,
so use it instead.

Allow users to override the default commands provided by the
mergetools/* scriptlets.

Users occasionally run into problems where they expect to be
able to override the built-in tool names.  The documentation
does not explicitly mention that built-ins cannot be overridden,
so it's easy to assume that it should work.

Lift this restriction so that built-in tools are handled the
same way as user-configured tools.  Add tests to guarantee this
behavior.

A nice benefit of this change is that it protects users from
having future versions of git trump their custom configuration
with a new built-in tool.

This reverts commit 25ae7cfd.

That patch does fix expansion of weird variables in some
simple tests, but it also seems to break other things, like
expansion of refs by "git checkout".

While we're sorting out the correct solution, we are much
better with the original bug (people with metacharacters in
their completions occasionally see an error message) than
the current bug (ref completion does not work at all).
