I=E2=80=99d consider this a bug in the user=E2=80=99s mind ;-) and would do=
 whatever is
easiest.

I think it=E2=80=99s 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=E2=80=99s best if =
it
doesn=E2=80=99t break overnight.

So we could remove -E from =E2=80=98--help=E2=80=99 and from the manual, bu=
t still keep
it around for a while.

WDYT?
