Many of the sort commands ignore case differences when comparing, if
@code{sort-fold-case} is non-@code{nil}.

-
- Diff mode is useful for editing patches and comparisons produced by
-the @command{diff} program. You can select Diff mode by typing
-@kbd{M-x diff-mode}; Emacs commands that compare files automatically
-select Diff mode. @xref{Top,, Diff, diff, Comparing and Merging Files},
-for more information about @command{diff} output formats.
-
- One general feature of Diff mode is that manual edits to the patch
-automatically correct line numbers, including those in the hunk
-header, so that you can actually apply the edited patch. Diff mode
-also provides the following commands to navigate, manipulate and apply
-parts of patches:
-
-@table @kbd
-@item M-n
-Move to the next hunk-start (@code{diff-hunk-next}).
-
-@item M-p
-Move to the previous hunk-start (@code{diff-hunk-prev}).
-
-@item M-@}
-Move to the next file-start, in a multi-file patch
-(@code{diff-file-next}).
-
-@item M-@{
-Move to the previous file-start, in a multi-file patch
-(@code{diff-file-prev}).
-
-@item M-k
-Kill the hunk at point (@code{diff-hunk-kill}).
-
-@item M-K
-In a multi-file patch, kill the current file part.
-(@code{diff-file-kill}).
-
-@item C-c C-a
-Apply this hunk to its target file (@code{diff-apply-hunk}). With a
-prefix argument of @kbd{C-u}, revert this hunk.
-
-@item C-c C-c
-Go to the source corresponding to this hunk (@code{diff-goto-source}).
-
-@item C-c C-e
-Start an Ediff session with the patch (@code{diff-ediff-patch}).
-@xref{Top, Ediff, Ediff, ediff, The Ediff Manual}.
-
-@item C-c C-n
-Restrict the view to the current hunk (@code{diff-restrict-view}).
-@xref{Narrowing}. With a prefix argument of @kbd{C-u}, restrict the
-view to the current patch of a multiple file patch. To widen again,
-use @kbd{C-x n w}.
-
-@item C-c C-r
-Reverse the direction of comparison for the entire buffer
-(@code{diff-reverse-direction}).
-
-@item C-c C-s
-Split the hunk at point (@code{diff-split-hunk}). This is for
-manually editing patches, and only works with the unified diff format.
-
-@item C-c C-u
-Convert the entire buffer to unified format
-(@code{diff-context->unified}). With a prefix argument, convert
-unified format to context format. In Transient Mark mode, when the
-mark is active, this command operates only on the region.
-
-@item C-c C-w
-Refine the current hunk so that it disregards changes in whitespace
-(@code{diff-refine-hunk}).
-@end table
-
- @kbd{C-x 4 a} in Diff mode operates on behalf of the target file,
-but gets the function name from the patch itself. @xref{Change Log}.
-This is useful for making log entries for functions that are deleted
-by the patch.
