    tdf#163894 sw DOCX: fix style-ref with character style
    
    Refer only the text formatted by character style instead
    of the whole paragraph text content, when style-ref
    field is used with character styles. Since a continuous
    text can consist of several hints, concatenate them.
    
    This fixes OOXML/DOCX interoperability, when not the
    full paragraph is formatted with the referred character
    style (see also DOCX unit tests of the upcoming commits).
    
    Follow-up to commit d4fdafa103bfea94a279d7069ddc50ba92f67d01
    "tdf#160402 writerfilter,sw: STYLEREF field can refer to character
    style" and commit 32c588dd1164aa2fc4c8120ddb74bd510cc082f9
    "tdf#86790: Add support for a word-style styleref".
