bug#65182: 29.1.50; c-ts-mode wants to outdent brace

[Robert Pluim]

>From an emacs-29 checkout:

src/emacs -Q src/process.c
M-g g 6025 RET
TAB ; nothing happens
M-x c-ts-mode
TAB ; the '{' moves left two spaces

The code around there looks like this:

#ifdef HAVE_GNUTLS
                  /* If we have an incompletely set up TLS connection,
                     then defer the sentinel signaling until
                     later. */
                  if (NILP (p->gnutls_boot_parameters)
                      && !p->gnutls_p)
#endif
                    { <= line 6025
                      pset_status (p, Qrun);
                      /* Execute the sentinel here.  If we had relied on
                         status_notify to do it later, it will read input
                         from the process before calling the sentinel.  */
                      exec_sentinel (proc, build_string ("open\n"));
                    }

Iʼd tell you what my libtree-sitter-c version was if I knew how to get
that information. I installed it on July 28th

(I donʼt think this is a duplicate of bug#65006, the patch there does
not affect this behaviour)
