question about "-E" option of compadd

[Han Pingtian <hanpt@xxxxxxxxxxxxxxxxxx>]

Hi there,

There is one statement about -E option of compadd in the manual:

    And because all but one empty string would otherwise be removed, 
    this  option implies  the  -V  and  -2 options (even if an 
    explicit -J option is given).

But isn't the action "all but one empty string be removed" implying a
"-1" option? "-2" option should keep all empty strings I think.

Thanks in advance!
