The problem was that I was treating the filenames the same in the
initial assignment (from the command line) and in the function's
internal assignment.  What I needed to do was realize that the first
time it's an array, and the second time it's an expansion of an array:

within the function:
    TOBACKUP=($@)

Before invoking the function:    
    TOBACKUP=("$@")    

Thanks for all your help!
