You really shouldn't be using -E outside of throwaway single-use code.
The problem with -E is that it's not forward-compatible. It defies the whole feature mechanism by enabling the highest possible feature set, breaking programs the feature mechanism is supposed to protect.

taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
