"GNU Emacs 18.57.19 of Sat Feb 23 1991 on bigbird (berkeley-unix)"

In GNU Emacs 18.57 (and 18.56), the various "print" routines don't start
at the beginning of the minibuffer after a call to "message".  For fun,
put this form in the *scratch* buffer and invoke it over and over:

    (progn
      (message "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz")
      (prin1 t t))

The minibuffer will show things like these:

    ABCDEt
    ABCDEFt
    ABCDEFGt
    ABCDEFGHt
    ABCDEFGHIt
    ABCDEFGHIJt
    ABCDEFGHIJKt
    ABCDEFGHIJKLt
    ABCDEFGHIJKLMt

and so on.

I'm including a fix that restores the behavior from 18.55 and earlier.
The fix is assuming that you want to keep the way "print" and "message"
are now sharing the same display buffer, the reason for which I don't
really understand.

Enjoy,
