Fix invalid default config

Serde has problems deserializing yaml files which contain sections
without any values. Since the `TERM` setting has been removed recently,
the `env` section was completely empty leading to deserialization
errors.

To resolve this the `env` section has been commented-out by default, if
the user wants to set a variable, it is now necessary to uncomment that
section.

Some minor tweaks have also been made to the existing `TERM` comments,
to clearly indicate these are value examples instead of comments.
