Where is my editor?

Hello,

After upgrading to 1.8 running commands  like comp, repl, etc, no longer
bring up my editor (vi) with the data already filled in. For example, to
type  this  email  I typed  comp,  and  then  it  entered some  kind  of
interactive dialog asking  me for the To header, the  Subject, and other
headers, then it printed
--------
and then let me start typing a message.  None of this is what it used to
be. I used  to type comp and  immediately vi would open with  all of the
headers and other details from my components in there.

Similarly, I used  to type repl (followed by my  favorite arguments) and
it would populate my  editor with a bunch of details  that I could edit,
but now I have some strange interactive thing.

What can I do to get the original behavior back?

Thanks,

Andy
