With "git submodule init" the user is able to tell git he cares about one
or more submodules and wants to have it populated on the next call to "git
submodule update". But currently there is no easy way he could tell git he
does not care about a submodule anymore and wants to get rid of his local
work tree (except he knows a lot about submodule internals and removes the
"submodule.$name.url" setting from .git/config together with the work tree
himself).
Help those users by providing a 'deinit' command. This removes the whole
submodule.<name> section from .git/config either for the given
submodule(s) or for all those which have been initialized if '.' is
given. Fail if the current work tree contains modifications unless
forced. Complain when for a submodule given on the command line the url
setting can't be found in .git/config, but nonetheless don't fail.
Add tests and link the man pages of "git submodule deinit" and "git rm"
to assist the user in deciding whether removing or unregistering the
submodule is the right thing to do for him. Also add the deinit subcommand
to the completion list.

Here we go, changes to v4 are:
- I decided to do the proposed special casing for "."; no messages
about uninitialized submodules will show up anymore (this is also
tested)
- The spelling fixes and better 'uninitialized' message Phil proposed
- Added the missing quotation for $sm_path in output strings
- "deinit" is added to the submodule completion list
- Added two missing "&&" in t7400
