Only first character underlined for redefined variable diagnostic

[rskvprd]

Also, it marked as unused for second declaration (maybe its ok)

I see that the unused warning should be suppressed for redefined variables, but what is the title trying to say? Is it saying that the diagnostics should show up for the first one, rather than be referenced by the diag on the second declaration? I guess for redefinition diags it could duplicate the diag for each duplicate, and have them reference eachother.

I think the red underline should be not only under first character, but under the whole word. That's all )

[rskvprd]

Regarding suppressing. Maybe it should be another issue

Same for unused-assertion-decl warnings
