Seems a useful idea and at worst, horizontally scrolling get used when
viewing the output.

Or if it does, then it doesn't especially matter that indentation simply
stops at this limit: it's arguably a feature rather than a limitation.

When viewing _complete_debug output, I nearly always use the less
feature to filter lines using &pattern, often using a pattern such as
\+_expand to filter by a particular function. With that in mind,
indentation before is more helpful.

Note the typo for PROMPT4.
