These regressions are still broken in the pretest, AFAIK.

 8429: `flush-lines' does not flush all it should
13061: redefining a function no longer cancels `debug-on-entry'
11314: incorrect Lisp indentation for `if' with `@@@@@@'
11325: wrong order in output of `substitute-command-keys'
11364: mouse selection then cursor movement no longer extends 
       selection in `delete-selection-mode'
