[Translators] Question about a message

[Fumio Nakayama]

Hi,

I'm reviewing and checking the translated messages on vlc-1.0.4.
But I think the following message is only defined, not used. The
message should be removed the code?

modules/visualization/visual/visual.c
    104 #define STARS_TEXT N_( "Number of stars" )
    105 #define STARS_LONGTEXT N_( \
    106         "Number of stars to draw with random effect." )

regards,
Fumio Nakayama
