- Fetching more than 100 gists is now supported
- The GraphQL query name is now `GistList` instead of `ListGists` for
consistency with other queries
- Avoid fetching unnecessary Files fields
- Gists are now rendered in the order that the API returned them in
- The gist timestamp for machine-readable output is now rendered in
RFC3339 format instead of in `time.Time.String()` format which is only
meant for debugging and is not considered stable
- Ensure newlines in gist description are rendered as spaces
It's not sufficient to use `Changed("public")` to test if a boolean flag
was activated, since the user might have passed `--public=false`.
Instead, check the true value of the flag.
The `--public` and `--secret` flags should be mutually exclusive, so now
if both are activated, `--secret` takes precedence.
