Indeed, I hadn't thought to run the tests, sorry. I've fixed my code
and modified the `block-order` test in order for it to pass.

The patch does modify the order of the tangled blocks. When several
blocks with different languages are tangled to the same file, they
used to be grouped according to language, and are now tangled in the
order in which they appear. I assumed this was an oversight in the
previous code, but since this test exists, maybe it was intended ?

Nicolas Goaziou wrote this test, perhaps he could comment on this.

Regards,
