I think the behaviour has changed in this patch.
It used to return `*SuppressionIsSpecific = false` when `ChecksStr = "*"`.
`"*"` is disabling all checks, not a specific check.
Now it returns `*SuppressionIsSpecific = true`. `Globs.contains(CheckName)` is
true regardless of whether `ChecksStr = "*"` or `ChecksStr = "check-name"`, so
it continues running onto line 353 and sets `*SuppressionIsSpecific = true` no
matter what.
