Split out basics into several sections

Makes it easier to read.  Also ensures any future additions just have
their own section rather than me appending the Lisp and forgetting to
update the text.

 * Basics
-Let's setup a few absolute essentials:
-- My name and mail address
-- File encoding (no "\r" characters at the end of lines, please)
-- Where to store backup files (~backup-directory-alist~)
-- Auto refresh buffers when a change occurs (~auto-revert-mode~)
-- Yes or no questions are less painful (~y-or-n-p~)
-- Make the "kill ring" work seamlessly with the clipboard
-- Deleting files or directories "trashes" them instead
-  - ... but when going on remote machines via [[info:tramp][tramp]],
-    don't try to trash the file to the local machine trash!
-- Font size based on the machine
-- Disable mouse usage where possible
-- Ensure when compiling the Emacs configuration, we only get messages
-  for really bad stuff
-
+We should introduce ourselves to Emacs properly - makes it easier for
+other tools.

+We'll want to use protected passwords and keys throughout our Emacs
+configuration.  This can be for stuff like [[*Mail][mail]] or
+[[*gptel][API based apps]].  We don't want these to be plain-text
+directly in our Emacs configuration for others to use.  Emacs has an
+in built [[info:auth#Top][auth]] system to keep these all in check,
+and we can ensure it's GPG encrypted.  Let's use no-littering to
+ensure it's in our Emacs directory but not right in the middle of it
+all.

+Emacs has an out of the box capability to make backup files of any
+buffer.  Let's make sure those auto-save files are in one place.
+#+begin_src emacs-lisp
+(setopt make-backup-files t
+        backup-directory-alist

+#+end_src
+
+I don't believe in the =\r= escape character.  It's weird to have that
+as an option when =\n= works just fine.  So let's make sure that Emacs
+also believes that.
+#+begin_src emacs-lisp
+(setopt buffer-file-coding-system 'utf-8-unix
+        save-buffer-coding-system 'utf-8-unix)
+#+end_src

+Make reading answers from the user short and sweet, and stop trying to
+use graphical dialogues.

+        use-dialog-box nil
+        use-file-dialog nil)
+#+end_src
+
+Deleting files should really "trash" the file instead (so we can
+recover them).  BUT when we're on a remote session, don't do that (see
+[[info:tramp][tramp]]).
+#+begin_src emacs-lisp

+Auto refresh buffers when a change occurs (~auto-revert-mode~).  Super
+useful when looking at the log of some program (in the form of a file
+or even just an ephemeral Emacs buffer), or when dealing with
+resources that may be edited by others.  I try to make sure we're
+reverting wherever possible.
