Git intermediate patches: with a piece less than a string

Question

I want to make an interactive patch from a unique commit. I would like to use output similar to

git diff --word-diff=porcelain [file]

for an interactive fix. Team

git add --edit

only offers hunk that are at least one line?

Purpose: I have a patch for text files, and I would like to change the change, as in "LibreOffice", accept or reject the changes.

---

Example:

Text file in one line:

echo "Thiis is a sentence with one wrong word. This is a clean sentence. Thhe laast one iss alwaays morre dificult" > text.txt

commit

git add text.txt
git commit -m "one"

File modification

echo "This is a sentence with one wrong word. This is a clean sentence. The last one is always more difficult" > text.txt

git add -e

should be automatically cut into 3 pieces

"Thiis" > "This"
"Thhe laast" > "The last"
"iss alwaays morre dificult"> "is always more difficult"

I can just get

--- a/text.txt
+++ b/text.txt
@@ -1 +1 @@
-Thiis is a sentence with one wrong word. This is a clean sentence. Thhe laast one iss alwaays morre dificult
+This is a sentence with one wrong word. This is a clean sentence. The last one is always more difficult

Note: in the best case, "does not introduce [confusing] changes to the index" (# EDITING PACKAGES)
