    You can edit a Diff mode buffer like any other buffer.  (If it is
- read-only, you need to make it writable first.  @xref{Misc Buffer}.)
- Whenever you change a hunk, Diff mode attempts to automatically
- correct the line numbers in the hunk headers, to ensure that the patch
- remains correct.  To disable automatic line number correction,
- change the variable @code{diff-update-on-the-fly} to @code{nil}.

-   Diff mode treats each hunk as an error message, similar to
- Compilation mode.  Thus, you can use commands such as @kbd{M-g M-n} to
- visit the corresponding source locations.  @xref{Compilation Mode}.
