This runs sprintf in two passes: once to apply the escape sequences and again to interpolate variables. This requires `%%` for the second pass, which _can_ be confusing. Maybe this approach is too much for the very simple highlighting in this version? But, it seems to work okay for elaborate color schemes, too. IMO it's easier to read and maintain than a bunch of conditional string appending. And it's simpler than the other templating approaches that I considered.

This first version is monochrome: only bold and underline highlights are added. A follow-up PR adds color.
