Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)
$ mkdir abc

$ echo "">abc/.keep

$ git status
On branch master
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        abc/

$ mv abc Abc

$ git status
On branch master
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        Abc/                                                      # rename
to Abc/ successfully

$ git commit -m "commit Abc/"                                     # commit

$ mv Abc abc

$ git status
On branch master
nothing to commit, working tree clean                             # cannot
rename again

$ git diff
>""

$ git add .

$ git commit -m "Cannot rename from Abc/ to abc/"
On branch master
nothing to commit, working tree clean                             # cannot
commit to right, keep old file name / folder name


What did you expect to happen? (Expected behavior)
It should be correct to new name although just change upper/lower case,
because other commiter can pull it from repo or improve reading clarity.

What happened instead? (Actual behavior)
can commit file/folder but cannot fix upper/lower case.

What's different between what you expected and what actually happened?
git unable to faithfully represent file/folder upper/lower case changes.

Anything else you want to add:

Yes, that is a restriction in Git, call it a bug, call it a missing feature.
Unless someone fixes it, the recommendation is still to use a workaround:

tb@pc:/tmp/ttt> git mv Abc tmp
tb@pc:/tmp/ttt> git mv tmp abc
tb@pc:/tmp/ttt> git status
On branch master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
        renamed:    Abc/.keep -> abc/.keep

tb@pc:/tmp/ttt>

Correct and very helpful suggestion.  Or get a better filesystem ;-)

Thanks.
