OCPBUGS-61061: add blank line before error in upgrade recommend --version output

[savio87]

Summary

When running oc adm upgrade recommend --version, the conditional-update risk message runs directly into the error line with no visual separation. This adds a blank line between the output and the error to improve readability.

Bug: https://redhat.atlassian.net/browse/OCPBUGS-61061

Changes

• Added fmt.Fprintln(o.Out) before the error return in the --version path of recommend.go (only when not in quiet mode)
• Updated 5 golden test fixtures to include the new blank line

Summary by CodeRabbit

• Bug Fixes
  • Improved upgrade recommendation output formatting by adding spacing before error messages and numbered entries.
  • Non-quiet mode now clearly separates unaccepted issue details from the resulting error.
• Tests
  • Updated upgrade recommendation examples to reflect the improved output formatting across supported scenarios.

Hi @savio87. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Hi, this is a small formatting fix that adds a blank line between the conditional-update risk message and the error line in oc adm upgrade recommend --version output.

The Jira issue (OCPBUGS-61061) currently targets 4.20.z, could a maintainer please update the target version to 5.0.0 and run /jira refresh?

Also requesting /ok-to-test when ready. Thanks!

According to the examples changes this is adding an extra newline where there already is one. Or were the examples wrong?

[savio87]

Good question! The blank line before error: in the existing fixtures comes from the test harness, not from the actual CLI output. In examples_test.go (line 104), the test joins stdout and error with \nerror: — that \n creates the visual separation you see in the fixtures. But in real CLI usage, Cobra prints the error immediately after stdout with no blank line, so the output looks cramped. This change adds the blank line to the actual program output (via fmt.Fprintln(o.Out)), which means the fixtures now need the extra line to account for both the program's newline and the test harness's newline.

[tchap]

Could we align the test harness to be consistent with the actual CLI output?
