When using the Navigator to insert a 'File' or 'Index' in a master document a text paragraph is always inserted with it which is shown as a 'Text' entry in the Navigator. The user can insert a 'Text' entry instead of having one automatically inserted when a File or Index is inserted.

Steps to repro:

1) Open a new Master Document file (Menu > File > New > Master Document)
2) Click on the 'Text' entry in the Navigator
3) tool box > Insert > File > insert a file
Navigator shows:
File 1
Text

4) Click on the File 1
5) tool box > Insert > File > insert a file

Expected results:
Navigator shows:
File 2
File 1
Text

Actual results:
Navigator shows:
File 2
Text
File 1
Text

This also happens when Index is inserted in place of the steps that insert a file.

Previous to the patch made for Bug 157315, 'Text' did not insert when a file was inserted. The bug there also caused the paragraph that is inserted before the linked file section insert to be overwrote by the linked file section which results in the file to be only shown in the Navigator.
