locate-library and visit

Hello I modifies locate-library replacing (if result (message "Library is file %s" result) (message "No library %s in search path" library))) result)) By (if result (progn (message "Library is file %s" result) (find-file result nil)) (message "No library %s in search path" library))) result)) then if the file is found it is also visted, the point is in most cases this could is a byte compiled file. Is there a possibility that xemacs would visit the source el file instead of the elc. Thanks Uwe Brauer
