Jens Lehmann 1cbd18300a mv: better document side effects when moving a submodule
The "Submodules" section of the "git mv" documentation mentions what will
happen when a submodule with a gitfile gets moved with newer git. But it
doesn't talk about what happens when the user changes between commits
before and after the move, which does not update the work tree like using
the mv command did the first time.

Explain what happens and what the user has to do manually to fix that in
the new BUGS section. Also document this behavior in a new test.

=========
NAME
----
git-mv - Move or rename a file, a directory, or a symlink
SYNOPSIS
--------
[verse]
'git mv' <options>... <args>...
DESCRIPTION
-----------
Move or rename a file, directory or symlink.
git mv [-v] [-f] [-n] [-k] <source> <destination>
git mv [-v] [-f] [-n] [-k] <source> ... <destination directory>
In the first form, it renames <source>, which must exist and be either
a file, symlink or directory, to <destination>.
In the second form, the last argument has to be an existing
directory; the given sources will be moved into this directory.
The index is updated after successful completion, but the change must still be
committed.
OPTIONS
-------
-f::
--force::
Force renaming or moving of a file even if the target exists
-k::
Skip move or rename actions which would lead to an error
condition. An error happens when a source is neither existing nor
controlled by Git, or when it would overwrite an existing
file unless '-f' is given.
-n::
--dry-run::
Do nothing; only show what would happen
-v::
--verbose::
Report the names of files as they are moved.
SUBMODULES
----------
Moving a submodule using a gitfile (which means they were cloned
with a Git version 1.7.8 or newer) will update the gitfile and
core.worktree setting to make the submodule work in the new location.
It also will attempt to update the submodule.<name>.path setting in
the linkgit:gitmodules[5] file and stage that file (unless -n is used).
BUGS
----
Each time a superproject update moves a populated submodule (e.g. when
switching between commits before and after the move) a stale submodule
checkout will remain in the old location and an empty directory will
appear in the new location. To populate the submodule again in the new
location the user will have to run "git submodule update"
afterwards. Removing the old directory is only safe when it uses a
gitfile, as otherwise the history of the submodule will be deleted
too. Both steps will be obsolete when recursive submodule update has
been implemented.
