When running `delete-duplicate-lines' in reverse mode (i.e., REVERSE is
non-nil) the topmost line is not deleted.  Please, see recipe:

1. Place the following lines in a buffer:

This is line A.
This is line B.
This is line A.
This is line C.
This is line A.

2. Select all the lines
3. Invoke "C-u M-x delete-duplicate-lines".
4. Result is:

This is line A.
This is line B.
This is line C.
This is line A.

The top line "This is line A." should have been deleted.

Thank you,
Adrián Medraño Calvo.

Thanks for confirming.  Since no objection to the patch was voiced, I've
pushed it to master as commit a8e1414c and am closing this bug.
