Xin LI 76628ce773 Save last displayed file by having the "last" pointer global and save it ...

during we show the first file's tail.  Instead of:

	tarsier% tail -f 1 2
	==> 1 <==
	foo
	bar

	==> 2 <==
	bar
	foo

	==> 2 <==
	bar2
	foo2

Now with this change, we have:

	tarsier% tail -f 1 2
	==> 1 <==
	foo
	bar

	==> 2 <==
	bar
	foo
	bar2
	foo2

While I'm there, move a comment to where it should belong to.  Also,
const'ify the "last" static because we will never need to change the
contents it points to.
