General purpose reformating and rewording in (a few places). This should
also make markdown linting happier.
Prefer back-ticks wherever useful and use `console` for code blocks to
be executed on terminal.
Also, update references links wherever possible (including update from
'http://' to 'https://').
Module `directory` used to set AUTO_NAME_DIRS. This was changed in

accidental omission that this commit fixes.
This was ported from Oh-My-Zsh and since have been disabled in it.
