Yes it's failing right now for me, like i wrote as note it started after system
updated.

That's probably why it started failing for me, because it started parsing the
single '$'.

Thanks

Escaping dots is a good idea and it should be done, I'll include it in this
patch, it's probably not worth to do in separate commit.  I'll explain the
changes little bit more in the commit message.

but this is probably intentional to exclude only the files we know about so if
someone else update a different file the syntax-check will fail.
