Issue 13366

When creating indexes I want to create an index looking like

|Tab. 1: This is a test table that is used only       |
|     to describe the problem that arises  with       |
|     the last line being not flexible enough .......1|
|Tab. 2: This is another test table that's used       |
|     for the same purpose ..........................2|

All I get at the moment is:

|Tab. 1: This is a test table thats used only to|
|     describe the problem that arises  with the|
|     last line being not flexible enough .....1|
|Tab. 2: This is another test table that is used|
|     for the same purpose ....................2|

The table's pages numbers should be on the right page border, all other lines 
before the last one however should not.

To reach above example I would not only need the first line to have an extra 
left indent, but also the last line of a paragraph to have an extra right 
indent.
