I’d consider this a bug in the user’s mind ;-) and would do whatever is
easiest.

I think it’s neither black nor white.

For instance, I use it at work for continuous integration.  I can
definitely migrate the scripts to the new syntax, but it’s best if it
doesn’t break overnight.

So we could remove -E from ‘--help’ and from the manual, but still keep
it around for a while.

WDYT?
