> Wondering what it would mean to support styled strings in error.

The main difficulty is that when the message is constructed,
we don't know if it will be printed to a stream that allows
styling.  However, we do have the machinery needed to strip
the styling when printing, so maybe that would be an option.

IMO the current situation, with different printf styles in
a single code base, is bad and is going to cause problems
again unless we change it at the root.
