I think the full attachment I sent earlier might have been a previous version so I am resubmitting it as a diff just in case:

Hi,

    I think the full attachment I sent earlier might have been a
    previous version so I am resubmitting it as a diff just in case:

Thanks for writing.

    I have bumped the copyright date.  I have also implemented a loop
    feature, which is common to many hello world programs, but which GNU
    hello lacks.

Is it so common?  I admit I've never come across this in a hello,world
before.  Kind of seems like feature creep to me :).  We already have
"yes" to output strings ...

Best,
Karl
