Re: splitting up --help text, sorting --where alphabetically

    Yes, that would be nice.  

Done.

    And while at it, maybe also remove the period at the end 

I see your point, but I didn't feel like changing all the help messages
in all the programs.  Besides, I like periods.  Sorry.

    when a description is more than one sentence, maybe 
    better use a semicolon instead.

I made that change in most cases, and a bit of other rewording.

Thanks,
