I do see what you're getting at. I agree to some extent. It is assumed that if the user does not use the -L -N or -S options, he/she would like the generated password to include at least one character from each. Thus separating each group and ensuring that one from each is generated prior to randomly selecting the remaining characters is optimal. But I think it should end there. IE if the user wants a nine character password, three of each letters, numbers, and symbols is not needed; rather one of each and the rest given an equal opportunity (Shuffling the results).

I did not intend for this to have any production value, but continually modifying the code with that goal in mind can only strengthen my education. Thanks again for the comments to all.
