recentchangesdiff: truncate extremely large diffs A diff was already truncated after 200 lines. But it could still be arbitrarily enormous, if a spammer or other random noise source likes long lines. That could use a lot of memory to html encode etc the diff and fill it into the template. Truncating after 100kb seems sufficient; it allows for 200 lines of up to 512 characters each.

html escaping complication Can't escape things to entities if the template then escapes the entities. (aggregate doesn't have this problem.)
