Display Features

• baud-rate is now a variable rather than a function. This is so you can set it to reflect the effective speed of your terminal, when the system doesn't accurately know the speed.
• You can now remove any echo area message and make the minibuffer visible. To do this, call message with nil as the only argument. This clears any existing message, and lets the current minibuffer contents show through. Previously, there was no reliable way to make sure that the minibuffer contents were visible.
• The variable temp-buffer-show-hook has been renamed temp-buffer-show-function, because its value is a single function (of one argument), not a normal hook.
• The new function force-mode-line-update causes redisplay of the current buffer's mode line.
