           Summary: FILEOPEN DOCX TOC style indent settings not imported

Example file from Word with TOC paragraph styles

Attached user made document has a TOC and there are custom styles (TJ 1-9)
defined for it. 
On the first level TOC entries is “TJ 1” style applied, on the second level
it’s “TJ 2”. These have 0 before/after/hanging indent set.
When opened in Writer the before/after/first line indents get crazy values,
making the first level TOC text unreadable.

More observations: “TJ 1” style is based on “Tartalom fejezetcím” style. Which
is based on “Címsor 2” style, that has 19.32 cm hanging indent – this shows up
in Writer; also 1 cm left indent which does not.
“Címsor 2” is based on “Címsor 1” which has 0 left and right indent, 0.75 cm
hanging. “Címsor 1” is based on “Normal” which has 0 left and right indent and
no hanging indent. 
I don’t see where the 15.5 cm before and -4,82 after indents are inherited in
Writer, but the 19,32 first line indent is from the “Címsor 2” style. See also
bug #132752

Also the “TJ 1-9” styles do not show up in the Styles sidebar at all.

Steps to reproduce:
    1. Open attached document

Actual results:
First level TOC entries unreadable due to spacing settings.

Expected results:
Readable TOC.

It might be possible that this has just uncovered something pre-existing.
