From: Mugdha Pattnaik <mugdhapattnaik@xxxxxxxxx>
Currently, running 'git submodule deinit' on repos where the
submodule's '.git' is a directory, aborts with a message that is not
exactly user friendly.
Let's change this to instead warn the user that the .git/ directory
has been absorbed into the superproject.
The rest of the deinit function can operate as it already does with
new-style submodules.
In one test, we used to require "git submodule deinit" to fail even
with the "--force" option when the submodule's .git/ directory is not
absorbed. Adjust it to expect the operation to pass.

submodule: absorb git dir instead of dying on deinit
Changes since v6:
* Edited commit message based on suggestions given.
* Passed correct arguments to absorb gitdir function; path and recurse
flag
* Modified behaviour of deinit such that it absorbs the gitdir even
when not forced.
Changes since v5:
* Fixed accidental submission of old version
Changes since v4:
* Changed test case from "! test -d" to "test_path_is_missing"
Changes since v3:
* Replaced 1 instance of the word "folder" with "directory"
* Fixed tab spacing
Changes since v2:
* Replaced all instances of the word "folder" with either "directory"
or "git dir"
Changes since v1:
* Removed extra indent within the if statements
* Moved absorb_git_dir_into_superproject() call outside the if
condition checking for --quiet flag

I have changed the 'cp -R ../.git/modules/example .git' to 'mv
../.git/modules/example .git' since, at the time of testing, the test
would fail - deinit now would be moving the '.git' directory into the
superproject's '.git/modules/' directory, and since this same directory
already existed before, it was causing errors. So, before running
deinit, instead of copying the '.git' directory into the submodule, if
we move it there instead, this functionality can be appropriately
tested.
Thank you, Mugdha

submodule: absorb git dir instead of dying on deinit
Currently, running 'git submodule deinit' on repos where the
submodule's '.git' is a directory, aborts with a message that is not
- exactly user friendly. Let's change this to instead warn the user
- to rerun the command with '--force'.
+ exactly user friendly.
- This internally calls 'absorb_git_dir_into_superproject()', which
- moves the git dir into the superproject and replaces it with
- a '.git' file. The rest of the deinit function can operate as it
- already does with new-style submodules.
+ Let's change this to instead warn the user that the .git/ directory

+ with the "--force" option when the submodule's .git/ directory is not
