Make action-only messages more compact
Many “messages” in a module workflow page don’t have actual “message content” (no comment).
Gitlab has a similar situation for issues where the timeline has both user comments and actions (changed labels, closed/reopened issue…), but actions are displayed in a more subtle manner than comments.
Can we make the actions more compact to improve readability? Note: DL actions can have no comment but still have files, which may or may not requiring diff.
