We could keep a header in the *-ts-mode.el file maybe?  Something like:


;;; Grammar version: 95e84b5493e8d21060f1a905d2e5e3c5590bae45


Anyway, I think until we have such a system in place, we should strive
to adhere to the most recent version of the grammar.  The diff is ok,
Vicenzo.  Would you like to add a proper patch or should I just do it?
I mean with a commit message and format like in CONTRIBUTE?
