Subject: Properly split up line blocks from line block pairs
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=61060096bdedbecd38a7100d83d05eb7fe1cb7c3;p=thirdparty%2Fjinja.git

Properly split up line blocks from line block pairs

This is necessary for us to do proper pairing of line blocks since
otherwise the rejection would disallow line blocks of any type.
