OK, but this is not what I observe: it reduces to just 1 line for Wrote /home/vinc17/a-very-very-very-very-very-very-long-directory-pathname/foo So this seems inconsistent. -- Vincent Lefèvre <vincent@HIDDEN> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)

If you switch to the *Messages* buffer, do you see there a message like this: Saving file /home/vinc17/a-very-very-very-very-very-very-long-directory-pathname ? If so, this is the long message, shown before the "Cannot write backup file", and it causes the mini-window to resize to 2 screen lines instead of just 1. This resize remains in effect for the following echo-area messages, to avoid the annoying back-and-forth jumps of the mode line. If you don't like this behavior, customize the option resize-mini-windows to the value t (and see its doc string for more details about this feature). This behavior is intended, not a bug.
