Incorrectly aligned block

[Blacksmoke16]

When using ACON::Helper::Formatter helper to format a block that has escaped content and in large mode, there are extra spaces on the first/last line.

require "athena-console"

app = ACON::Application.new "MyApp"

app.register "test" do |_, output, cmd|
  formatter = cmd.helper ACON::Helper::Formatter

  output.print formatter.format_block "<info>some info</info>", "error", large: true

  ACON::Command::Status::SUCCESS
end

app.run
