Not sure I understand: we let-bind inhibit-modification-hooks in C,
via specbind, and that binds the global value, since
inhibit-modification-hooks is not a per-buffer variable.  Or am I
missing something.

Do you mean we should add a new specbind_local function that makes
only a buffer-local let-binding?
