Subject: [PATCH 07/10] completion: bash: refactor _get_comp_words_by_ref()
Date: Wed, 4 Nov 2020 11:47:13 -0600 [thread overview]
Message-ID: <20201104174716.783348-8-felipe.contreras@gmail.com> (raw)
In-Reply-To: <20201104174716.783348-1-felipe.contreras@gmail.com>
We don't need a separate function to do what we already know we want to
