Document that tar archives are now properly terminated.
Commit 5a1007a5088cd6ddf892f7422ea8dbaef362372f changed the server
behavior, but I didn't notice that the existing behavior was
documented, and therefore did not update the documentation.
This commit does that.
I chose to mention that the behavior has changed rather than just
removing the reference to a deviation from a standard. It seemed
like that might be helpful to tool authors.
