I am against automatic escaping, because it makes it impossible to have
a & separate two commands. The user should do the escaping.
Generally, Vim should do as little as possible. We currently don't do
any of this ^ escaping, I am very hesitant to start this now.
Also because it is unclear to me where the un-escaping is done. The echo
example is confusing.
