• change e_pre to htmlize and let it convert successive spaces to using   for all but the first, wrap tab characters in <span style="white-space: pre;">…</span>, etc.

The intent is that for output where we need to preserve formatting, *but* want to have word wrap, we do:

    puts '<pre style="white-space: normal;">' + htmlize(str) + '</pre>'
