treesit.c and treesit.el got, and keep getting, significant changes on
the master branch, so when people report bugs for Emacs 30, I cannot
always be sure that the bug exists on the release branch as well, nor
that the patch is appropriate for the release branch (i.e. doesn't
modify code that is different on master).  That's why I asked.
