Subject: [PATCH] Fill background for borderless one-line paragraph

Previously when we had a Par with Width > len(Text) and custom BgColor
on the underlying Block, it would skip the first row. This means that
it's impossible to have a colored line wider than text width.
Block should offset indexes by 1 only if border is present.
