    src/roff/groff/tests/*: Remove redundant syntax.
    
    "exit $?" at the end of a shell script means the same thing as just
    plain "exit" which means the same thing as just falling off the end
    of the script.  The exit status of the script is that of the last
    command executed.
    
    I can't find the exact spot in POSIX 2017 that mandates this, but none
    of the following shells screw it up:
        bash 5.0
        dash 0.5.10.2
        ksh 93u+20120801
        mksh 57
        posh 0.13.2
        yash 2.48
        zsh 5.7.1
