Comment operator

Is it BBCODE?
It does not follow BBCODE's naming convention, yet BBCODE is required to multiquote.

Also, [o] is the only tag subject
to operator overloading.

Not overloading, the other thing, I apologise. Context-sensitivity. Usually it is overline, but when used in quotes it makes a quote multiline.

Quoting (> ) should not be BBCODE as it does not use brackets.
But they must be, as they interact with BBCODE directly to produce multiquotes.
