Implement import of bullets and numbering which use the old Word 6.0/Word 95 format from RTF. This includes, but is not limited to, the following RTF tags: \pnlvlN, \pnlvlblt, \pnlvlbody, \pnlvlcont. See RTF specification, "Word 6.0 and Word 95 RTF" heading for full description.
WordPad and some legacy systems export lists with this formatting, so the construction is relatively widespread.
According to the specification, if RTF reader doesn't support specific bullets/numbering tags, it can use the \pntext tag to read the bullets/numbering as plain text; but currently WordsProcessing always ignores the \pntext tag. Because of this, the bullets or numbers of lists in the old format are missing after import.
