When writing an application that uses these string capabilities, the
pairs should be first checked to see if each capability in the pair is
For example, the DEC vt220 supports most of the modes:

- none none \E[0m

- p7 invis \E[0;8m
- p8 protect not used

We begin each escape sequence by turning off any existing modes, since
there is no quick way to determine whether they are active. Standout
