RFC: Styling messages and comments separately

[MrCoder]

In our current implementation, we use the following syntax to control the style for both comments and messages. However, it would be good (?) that we could control them separately.

// [red] comments
A.method

The proposed solution:

1. <red> controls comment only;
2. (red) controls message only;
3. [red] controls both comment and message.

All style brackets should appear before the first non-empty character

[MrCoder]

All style brackets should appear before the first non-empty character

Yes. And they should appear only at the last line of comment. Only one type of styling annotation should appear.

Wrong:

// [red] comment
// another line of comment

Wrong:

// <red>(blue) comment

[dyon21]

Why do we not allow multiple annotation types in one comment? Users may want to set different styles to both comments and messages respectively.
