    Remove unnecessary dash to appease old csh
    
    /bin/csh on Red Hat 5 that I use is a symlink to tcsh version 6.14 built 
over 10 years ago.
    This csh fails due to presence of the dash.
    Removing the dash resolved the problem for me.
    I don't know what the purpose of the dash was in the first place.
    If it was an optional character, then I would suggest that you remove this 
to allow older shells to work.
