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://').
In homebrewed environment, avoid using `brew --prefix nvm` which is
ruby based and is super slow. Instead, rely on homebrew standard
behavior wherein all installed packages are available in canonical
path $(brew --prefix)/opt/<package> (for nvm it would obviously be
`$(brew --prefix)/opt/nvm`).
NB: `$(brew --prefix)` (without additional argument) is a simple shell
shortcut and doesn't have the same performance impact.
This change fixes a bug where no command can be found
(e.g. `ls`) due to the $path array being set to two elements,
one of them with all the previous paths separated by spaces.
This makes zsh break $PATH, instead of colons there are
spaces, and nothing works.
The idea is to have the array be set leveraging the word splitting
that we usually are told to avoid by quoting.
This is done to make it easier to not show node-info in themes
when no node version is currently in use. This is consistent with
how the Python module's python-info works.
