Subject: 29.0.60;  treesit-beginning/end-of-defun problem with macros in c-ts-mode
--text follows this line--

treesit-beginning/end-of-defun in c-ts-mode not work correctly with macros.

For example, in the following codes:

#define SWITCH()
#define CASE(name)		case name:

void func(int i)        // LINE_E
{
    SWITCH(i)           // LINE_D
    {
        CASE(A)         // LINE_C
        {
            ;
        }
        CASE(B)         // LINE_B
        {
            ;           // LINE_A
        }
    }
}

When cursor is at LINE_A, and stoke `C-M-a`, cursor will go to LINE_B;
then `C-M-a` again, cursor goes to LINE_C, then `C-M-a` again, LINE_D,
and `C-M-a` again, finally to LINE_E...


Regards...
