Brought back my file listing when opening eshell

My life is already a dad joke.

Why didn't I think of putting the directory and git branch on the
header-line!?

+** Directory Notification
+While most people put the “current directory” in their shell prompt, I’ve always found that pretty distracting, difficult when copy/pasting commands, and cuts out on the length of my commands (which might be a good thing, tbh).

 ** Navigation and Keys
 Along with the regular Emacs keybindings, Eshell comes with some interesting features:
 - ~M-RET~ gives you a prompt, even when you are running another command.  Since =eshell= passes all input to subprocesses, there is no automatic input queueing as there is with other shells.

 ** Opening Banner
-Whenever I open a shell, I instinctively type =ls= … so why not do that automatically? The [[elisp:(describe-variable 'eshell-banner-message)][eshell-banner-message]] variable, while defaults to a string, this variable can be a /form/ (an s-expression) that calls a function, so I made a customized =ls= that can be attractive:
