Clear doesn't do anything to differentiate new output from old.

It makes an entire blank line, which is sufficient if you have a lot of textual output. It also gets rid of the old stuff from the screen - if you're running a window manager, you can then scroll up if you need the old stuff.

I use `clear` but in tmux, the whitespace produced by `clear` disappears, so it's the same as pressing <Enter> :(
