*nix Server Console Behavior

The server console behaves strangely in MC 1.7.2 . It no longer displays colored text, the prompt character (>) is gone, and if a new message appears in the console while I'm attempting to type a command, the command I'm typing winds up getting mangled when the new message appears. It feels more like I've run tail -f on the server.log, and am typing into a really buggy prompt beneath the output.
