Need help w/ ada-mode.el under Emacs 21.

["Bobby D. Bryant" <bdbryant@mail.utexas.edu>]

After a general system upgrade my Ada-mode for Emacs is behaving
differently, and I'm having trouble restoring the earlier behavior.

The behavior that I want to suppress is that whenever you press return on
an empty line to create more whitespace I get an indentation on the new
line, and I want the cursor to stay at the left margin unless I press the
tab key.  Previously it would guess an indentation if I were in the middle
of a declaration or a statement, but not otherwise, and that is the
behavior that I would like to restore.

I see that I can suppress re-indentation of the *current* line by adding
(setq ada-indent-after-return nil) to my ~/.emacs, but that's not what I
want to change -- I want to change indentation of the line where the
cursor ends up after pressing return.  Nor do I want to disable
indentation altogether; I just want to disable contextless indentation. 
(While working on complicated problems I like to put "lose end" comments at
the left margin so I can find them more easily by skimming, and it's
really annoying to have to move every line back to the margin by hand.)

Any help would be appreciated.
