error in join --help

[Toth Alexandru]

Hi,

help for join command states:

 -a FILENUM        print unpairable lines coming from file FILENUM, where
                     FILENUM is 1 or 2, corresponding to FILE1 or FILE2


Maybe it should be:

 -a FILENUM        print joined lines 
                     and unpairable lines coming from file FILENUM, where
                     FILENUM is 1 or 2, corresponding to FILE1 or FILE2

For example option -v is correctly documented.
