Subject: bug#71205: 29.3; Automatic indentation of c-ts-mode doesn't work well for me.
Date: Sun, 26 May 2024 13:32:37 +0900

Dear emacs-devel maintainers.

Automatic indentation of c-ts-mode doesn't work well for me.
I tried it in two environments, and neither worked properly.

- homebrew cask emacs 29.3 on MacBookAir M1 2020 Sonoma 14.4.1
- emacs 29.1 on FreeBSD 13.2-RELEASE-p3

I have elpa package `~/.emacs.d/elpa/treesit-auto-20240511.1425` .
I have the following language bundles in `~/.emacs.d/tree-sitter` on 
MacBookAir,

-rwxr-xr-x 1 XXXXX staff 664K  5 23 17:41 libtree-sitter-c.dylib
-rwxr-xr-x 1 XXXXX staff 3.8M  5 23 17:41 libtree-sitter-cpp.dylib
-rwxr-xr-x 1 XXXXX staff 648K  5 23 17:44 libtree-sitter-python.dylib

and on FreeBSD,

-rwxr-xr-x 1 XXXXX XXXXX 618K May 23 23:12 libtree-sitter-c.so
-rwxr-xr-x 1 XXXXX XXXXX 3.7M May 23 23:12 libtree-sitter-cpp.so

I have a simple `~/.emacs.d/init.el` the follows,

-------------- init.el begins ---------------------
(use-package treesit
  :config
  (setq treesit-font-lock-level 4))

(use-package treesit-auto
  :ensure t
  :config
  (setq treesit-auto-install t)
  (global-treesit-auto-mode))
---------------- init.el ends ---------------------

The steps to reproduce are as follows.

1. Start emacs.
2. Open the C source code file and write the following content.

----------- c source code file begins -------------
void test(void)
{
  do🔳
----------- c source code file ends ---------------

3. Place the cursor after `do` and press Return.

Expected behaviour is automatic indentation. I want to move the cursor 
to the 5th column of the next line.
However, the observed behavior is NOT indentation. The cursor moves to 
the 1st column of the next line.
For reference, the column position of `do` was moved correctly the 3rd 
column with automatic indentation.

Thanx.
