test document

Problem description: 
Linux Libertine G by default handles the standards ligatures, like ff, ffi,
ffl, tt.
On hyphenated words, the ligature is not omitted.
Using the test text "Lorem ipsum differenza"
I get this beaviour:

Lorem ipsum diff-
ferenza

while it should be:

Lorem ipsum dif-
ferenza

Linux Libertine offers a variant, "Linux Libertine G:ligc=1" which should
correct ligatures on hyphenated words. But apparently it is ignored on the
latest version of Libreoffice.

Note: I'm using the Italian hyphenation.

Steps to reproduce:
1. Enable hyphenation on the current paragraph
2. Set "Linux Libertine G:ligc=1" as the current font
3. Paste same test text that gets hyphenated on a standard ligature 

Current behavior:
A ligature is added before the hyphenation line.

Expected behavior:
No ligature should be added.
