    m4/groff.m4: Revert paranoid shell assignments.
    
        My quotations of variable test(1) arguments were fine, but the
        ones to variable assignments were unnecessary.  Since, per the
        Autoconf manual, quoting RHS variables in assignments is
        actually _less_ portable, revert them.  (The way I'll think
        about this is going forward is "word splitting occurs before
        parameter expansion".)  Thanks to Colin Watson for the tip!
