Make git status show unmodified/unchanged tracked files?

Question

Here is a brief snippet example (which you can paste in your Linux terminal), creating a new git repository and adding some files to it (using git version 1.7.9.5):

cd /tmp/
mkdir myrepo_git
cd myrepo_git/
git init
git config user.name "Your Name"
git config user.email [email protected]
echo "test" > file_tracked_unchanged.txt
echo "test" > file_tracked_changed.txt
echo "test" > file_untracked.txt
git add file_tracked_unchanged.txt 
git add file_tracked_changed.txt
git commit -m "initial commit"

Now, after the initial commit, I want to change the file_tracked_changed.txt files, and keep the others (here, only file_tracked_unchanged.txt) unchanged for the next commit. Below is a snippet which demonstrates that, and the diverse outputs of git status vs git ls-files (git shell output is prefixed with #):

echo "test more" >> file_tracked_changed.txt

git status -uno
# # On branch master
# # Changes not staged for commit:
# #   (use "git add <file>..." to update what will be committed)
# #   (use "git checkout -- <file>..." to discard changes in working directory)
# #
# # modified:   file_tracked_changed.txt
# #
# no changes added to commit (use "git add" and/or "git commit -a")
git status
# # On branch master
# # Changes not staged for commit:
# #   (use "git add <file>..." to update what will be committed)
# #   (use "git checkout -- <file>..." to discard changes in working directory)
# #
# # modified:   file_tracked_changed.txt
# #
# # Untracked files:
# #   (use "git add <file>..." to include in what will be committed)
# #
# # file_untracked.txt
# no changes added to commit (use "git add" and/or "git commit -a")
git status -uno --short
#  M file_tracked_changed.txt
git status --short
#  M file_tracked_changed.txt
# ?? file_untracked.txt
git ls-files -v
# H file_tracked_changed.txt
# H file_tracked_unchanged.txt

git add file_tracked_changed.txt

git status -uno
# # On branch master
# # Changes to be committed:
# #   (use "git reset HEAD <file>..." to unstage)
# #
# # modified:   file_tracked_changed.txt
# #
# # Untracked files not listed (use -u option to show untracked files)
git status
# # On branch master
# # Changes to be committed:
# #   (use "git reset HEAD <file>..." to unstage)
# #
# # modified:   file_tracked_changed.txt
# #
# # Untracked files:
# #   (use "git add <file>..." to include in what will be committed)
# #
# # file_untracked.txt
git status -uno --short
# M  file_tracked_changed.txt
git status --short
# M  file_tracked_changed.txt
# ?? file_untracked.txt
git ls-files -v
# H file_tracked_changed.txt
# H file_tracked_unchanged.txt

What I'm looking for, is a command which will show all tracked files in a directory (which git ls-files -v does), with their accurate repository status (which git ls-files doesn't show, as it shows H as status for all tracked files). For instance, I'd like to obtain something like the pseudocode:

git status-tracked
# M file_tracked_changed.txt
# . file_tracked_unchanged.txt

... where the dot . would a symbol indicating a tracked, but unchanged file (if I recall correctly, SVN may use a U character for these).

Ultimately, I'd like to also show the status of all files in a directory, as in the pseudocode:

git status-tracked-and-untracked
# M file_tracked_changed.txt
# . file_tracked_unchanged.txt
# ?? file_untracked.txt

... but it's more important to me to get to the status of all tracked files, as in the pseudo git status-tracked above.

Any command in git, that already does something like this?

Quick one-liner that works on Linux:

sort -uk 2bi <(git status -s) <(git ls-files | sed 's/^/ . /')
