It would be nice to be able to turn on and off styles relative to the current settings.

For example, using - could disable a style, and + could enable a style.

Some examples:

• --style=full --style=-numbers -- Everything except line numbers.
• --style=full,-numbers -- Everything except line numbers.
• --style=+headers,+rule,-changes -- Default, with headers and rules without changes.
