there's no error when jinja template is broken

[ivanov]

at the bottom of http://www.dexy.it/guide/getting-started.html#showing-code-and-output

it says:

Remove one of the curly brackets { from the hello.txt file and try to run dexy again. You should get an error message because the jinja processor can't parse the file. Fix the file and make sure dexy runs with no more errors.

Actually doing that doesn't report errors and simple plain-texts the "broken" template shortcut.

Maybe change it to something like

Remove one of the curly brackets `{` from the `hello.txt` file and try to run dexy again. You should see that the corresponding portion of the output file now doesn't  get transformed by jinja.

this is using jinja2.__version__ '2.7'
