Can someone please tell which problem(s) this is supposed to fix, and
on what branch?  This bug report has "29.0.60" in the title, but it
starts with describing what happens on master.  On the emacs-29 branch
C-M-f doesn't use treesit capabilities, at least not in c-ts-mode.  So
I'm confused regarding the scope and the purpose of this proposal.
