I've switched from 21 to 23 a few weeks ago and don't recall any particular
issues (and I'm a fairly hardcore emacs user with pretty complex configuration
and many third-party packages -- my emacs config has 182 matches for
require\|autoload).

I think as the author I would have noticed by now if it didn't :)

Nope. Try  ``run -d myscript`` (and ``?run`` for more info). 

I must admit that this doesn't work properly for me though -- I don't get
stepping through the corresponding source in emacs. ``M-x pdb`` works with pdb
as debugger but not with pydb; maybe the problem is missing pydb support in
the relevant regexps?

I can't devote any time to this at the moment, but I'd be pretty interested in
having this working -- so I'd appreciate a note if someone figures out what's
going on (and if a change to ipython.el is needed I'll make sure it gets in).

It's already there -- I'm using 0.7.4 svn (which is the ubuntu feisty
package), so I think it should also work for you.

I'd type something like ``run -<Meta>+<P>`` (with M-p bound
to `comint-previous-matching-input-from-input') or M-r, which is even fewer
keystrokes.
