@code{mode-require-final-newline}. By setting the latter variable,
you can control how these modes handle final newlines.
+@vindex write-region-inhibit-fsync
+ When Emacs saves a file to disk, it issues an @code{fsync} call to the
+operating system to ensure that your data has indeed reached the media.
+This is important for safety if the system crashes or in case of power
+outage. However, it can be disruptive on laptops using power saving
+because it forces the system to spin up the drive each time you save a
+file; the variable @code{write-region-inhibit-fsync} disables this
+synchronization. This may result in data loss, use with care!
