The importance of a good command line prompt

Thanks for the nice write up. I have a prompt spanned over two lines, with just a '$ ' on the second line so that you can have a very long first line (deep nested dir, long git branch name, timestamps, etc) without filling room for the actual command.

Another nice tip, which is not really related to this, is getting used to use `fc` (or CTRL+X E) to edit a command.
