Raw blocks report incorrect identation

[mriska]

Raw blocks seem to get incorrect indentation calculation which causes false positives.

The following template:

{{{{if isMorning}}}}
  Good Morning
{{{{/if}}}}

Gives the following error message:

Incorrect indentation for `if` beginning at L1:C0. Expected `{{/if}}` ending at L3:C11 to be at an indentation of 0 but was found at 4."
