Re: Equation display styles and context-sensitive rendering

[Jeff Kingston]

+       StyleCopy(new_style, *style);
+       context_key(context(new_style)) = key;
+       context_value(context(new_style)) = value;
+       context_previous(context(new_style)) = &context(*style);

Unless I've missed something, there is a bug here:  I don't
see any creation of a new context object, this code overwrites
the object at the front of the list rather than adding to the
front of the list.

ps I agree with the general approach of adding to the front
of a list.  It means you don't have to copy the list when
you copy the style; and linear search down the list for
the first occurrence of what you want is quite fast enough.
