Attached below are two small changes that allow slime to complete filenames that have spaces in them. Filename completion is great--I admit to being mystified for a moment when I (unconsciously) hit tab while typing source code and slime did what I meant. The caveat is that with this change slime will try to complete any quoted string as a filename... but for me, the filename completion is worth it. Finally, the diff is against a slightly old version but I checked against the latest CVS version and the relevant lines of code haven't changed. Also I'm using a ~May 2006 build of Emacs from CVS.
