I don't understand this change. If the file doesn't exist then OPEN will just fail (which is already handled). And even if PROBE-FILE succeeds, OPEN can still fail, e.g. because some other process deleted the file in between.
Which problem does the patch solve?

The first change made to a buffer that was created using find-file on a file that didn't yet exist would cause a Slime REPL to pop up and take focus. The mode-line of the original buffer would show "(Lisp Slime|eval...)". Some features like arglist-echoing would temporarily stop working in all Slime buffers.
This only occured with fairly recent versions of Slime, with both SBCL and CMUCL. Nothing out of the ordinary in either *inferior-lisp* or *slime-events*.
