Draft: Exit non-zero when requested info is not available
When requesting information that was not available, apk would yield an
empty response, which can be ambiguous. E.g.: apk info --triggers ruby
would return an empty response, which could mean either (1) information
not available, or (2) package ruby has no triggers.
When the information is not available, exit 1 instead.
- TODO: 1 is not the correct exit code. I'm not sure which one would be best.
- TODO: Some flags (e.g.: --rinstall-if) return partial results when related packages are not installed. This should at least be well documented.
