Extends does not work when template has BOM

[JohnAZoidberg]

This is the beginning of my file:

$ head -n2 home.html.tera 
{% extends "template" }
{% block content %}

and in hex dump:

$ xxd home.html.tera | head -n2
00000000: efbb bf7b 2520 6578 7465 6e64 7320 2274  ...{% extends "t
00000010: 656d 706c 6174 6522 207d 0a7b 2520 626c  emplate" }.{% bl

when trying to render the template Tera panics with:

Parsing error(s): 
* Failed to parse "templates/home.html.tera"
 --> 1:2
  |
1 | {% extends "template" }␊
  |  ^---
  |
  = unexpected tag; expected end of input or some content

When running dos2unix home.html.tera, which removes the BOM it works. This is the UTF-8 BOM but I assume it's the same for other encodings as well.

I'm using tera 1.5.0.

Ah damn, must be something in the grammar...
