There was no reason to rush this to the repository.  Paul raises valid
concerns, some of which I had as well.  Also, the commit message
describes something that is very different from the code that was
actually pushed.

I think a version with a fixed-size automatic buffer and a loop using
it to write the message in chunks, would be a much cleaner solution
than allocating the buffer off the heap.

There's also a possibility to use the null byte that we
always/normally have in strings after the last byte.  'fwrite' doesn't
need it, so we could replace it with a newline, write the message,
then replace the newline back with the null byte.  This is somewhat
hacky, but it eliminates the need for a buffer and a loop.
