    REGRESSION: Fix issues found by by review
    
    Ben reported following potential problems:
    
    I think that if the DEPENDENT subcommand is given twice (a user error), then
    the variables specified the first time will be silently leaked.
    
    cmd_regression() has two local variables named 'i'.
    
    I don't understand why "struct workspace" has a member 'psw' that is a
    dynamically allocated array, because it looks like each element of the array
    is used only during processing a single split file group.  That is, I think
    that 'psw' could be just a singleton, instead of an array.
    
    I think that fill_all_vars() is wrong: if an absent var follows a not-absent
    var, then vars[] will be filled with a gap and there will be a write into
    unallocated memory.

    Avoids shadowing variable in lower scope.  suggested by Ben Pfaff
