[REVIEW:3-5] fdo#47764 fix RTF import of automatic paragraph background color

[Miklos Vajna]

Hi,

See
http://cgit.freedesktop.org/libreoffice/core/commit/?id=e8706d7

Regression from 3.4; backported patch attached.

(v1.9.1 of the spec on page 23 states this detail that 0 means
"automatic" color, which is the Writer default.)

Thanks,

Miklos
