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. MFC After: 1 week
