In `Colored and styled underlines` it's proposed that the SGR codes
\e[4:4m and \e[4:5m are used to add a dotted or dashed underline to the
rendering context respectively. This commit prepares the necessary
changes to add the two additional underline style, while still rendering
them as a normal underline and curly underline.
