Patch Set 2:

Right, the whitespace errors are away now. My fault: I looked at a diff between patchset #1 and #2 which ignored whitespaces.

Regarding the commit message: I cannot see any comments from you when they are still in "draft" status. You have "Review" the patchset where you put your comments to publish all comments. From change overview click on "Patch Set 1", press the "Review" button in the Patch Set 1 section and then press "Publish comments"
