This commit expands on @nobe4 initial work by bringing the owner and repository name to the most obvious issue and PR number output use cases before making a second pass for any edge cases.
- `issue close` no longer fetches all issue fields and thus avoids the
problem when loading failed due to token not having access to projects
- `issue close` now accepts either issue or pull number as argument.
For operations such as closing an issue or merging a PR, we would
display the success icon (a checkmark) in red and magenta colors,
respectively, to reflect the latest state of the record operated on
(red: closed; magenta: merged).
This was always confusing to me, seeing it both in code and in the UI,
because I'm instinctively thinking that it's a bug and have to remind
myself that it's by design.
