The bottom line is that escape > sequences are for communicating with the user's peripheral devices. Nice summary. But, it is also communicating with my peripheral device. > Since yours may not be the same as the user's who created the log, you > don't even know that yours will respond the same way. Sounds like something we need to standardize. Although, from the many build logs I have came across; it does respond fairly well in most of the cases, I am yet to come across a build log that displays bad.
