Prose with markup needs more line spacing [legibility 5/6]

[Texas Cyberthal]

Code requires less line spacing. It has more whitespace, fewer capital
letters, and no markup such as underlining. Code is read differently
than prose; it requires less sequential scanning.

Prose has big blocks of text with taller capital letters that must be
scanned sequentially. The tall bits bump into lines above and below.
Org prose adds markup. Underlining and all-caps tags are common. This
requires a bit more line spacing for optimal legibility:

#+begin_src elisp
;; prose with markup needs more line spacing
(defun leo-space-lines ()
  (setq line-spacing 0.175))
(add-hook 'org-mode-hook 'leo-space-lines)
#+end_src
