Example of soft hyphen being ignored in cross-reference in paragraph 2 but ZWSP
being honoured in cross-reference in Paragraph 4.

This bug is also present in 3.5.0 Beta2.

Problem description: 
When a cross-reference is inserted as a reference, soft hyphens in the text
being referenced are ignored.

Steps to reproduce:
1. In a new paragraph, enter string of letters and digits long enough to cause
a line wrap.
2. Insert a soft-hyphen, e.g. by ctrl/-, so that the text only breaks at that
point.
3. Create a new, empty paragraph with the same styling as the paragraph at Step
1.
4. Select text entered at steps 1 and 2, and create a reference by insert,
cross-reference, set-reference, entering a name, and clicking insert in the
dialogue box.
5. Create a cross-reference in the new, empty paragraph by insert,
cross-reference, choosing Reference in 'Insert reference to', selecting the
name from Step 4 and clicking insert in the dialogue box.

Observed behaviour:
The cross-reference text breaks not at the location of the optional hyphen, but
when the cross-reference text reaches the end of line.  This is observed in
both the writer display and in exported PDF.

An example of what is saved in content.xml is the following:

<text:p text:style-name="P1"><text:reference-mark-start
text:name="testing"/>verylongstringpt1­verylongstringpt2<text:reference-mark-end
text:name="testing"/></text:p>
<text:p text:style-name="P1"><text:reference-ref text:reference-format="text"
text:ref-name="testing">verylongstringpt1verylongstringpt2</text:reference-ref></text:p>

There is a soft hyphen in the reference definition (between 'pt1' and 'very'),
in the first paragraph, but not in the cross reference (the second paragraph). 

Correct behaviour:
The text of the cross-reference should both break at the point of the soft
hyphen rather than between letters and digits.

Remark:
This problem does not occur with zero-width spaces.  They are stored in their
own text:span elements, and the ZWSP (U+200B) character occurs within a
text:span element in the cross-reference. (This partial work-around is more
difficult to apply in 3.5.0 beta2 because ZWSP no longer appears on the insert,
formatting mark menu.  Not all keyboards include ZWSP.)
