# Description
- Refactor code to be simpler.
- Make the mentioned changes.
- `scopeguard` is added as a direct dependency. Helps simplify the code.
Rather than roll an ad-hoc version of it myself, I thought it would be
better to use `scopeguard` as it was already an indirect dependency.
# User-Facing Changes
- Add `--beginning` flag, which is used to validate the response and
provide early errors in case of unexpected inputs.
- Both `terminator` and `beginning` sequences (when provided) are not
included in the command's output. Turns out they are almost always
removed from the output, and because they are known beforehand they can
be added back by the user.
