Refreshes the specified patch, or the topmost patch by default.
Documentation that comes before the actual patch in the patch file is
retained.

It is possible to refresh patches that are not on top.  If any patches
on top of the patch to refresh modify the same files, the script aborts
by default.  Patches can still be refreshed with -f.  In that case this
script will print a warning for each shadowed file, changes by more
recent patches will be ignored, and only changes in files that have not
been modified by any more recent patches will end up in the specified
patch.

-p n	Create a -p n style patch (-p0 or -p1 supported).

-p ab	Create a -p1 style patch, but use a/file and b/file as the
	original and new filenames instead of the default
	dir.orig/file and dir/file names.

-u, -U num, -c, -C num
	Create a unified diff (-u, -U) with num lines of context. Create
	a context diff (-c, -C) with num lines of context. The number of
	context lines defaults to 3.

-z[new_name]
	Create a new patch containing the changes instead of refreshing the
	topmost patch. If no new name is specified, \`-2' is added to the
	original patch name, etc. (See the fork command.)

--no-timestamps
	Do not include file timestamps in patch headers.

--no-index
	Do not output Index: lines.

--diffstat
	Add a diffstat section to the patch header, or replace the
	existing diffstat section.

-f	Enforce refreshing of a patch that is not on top.

--backup
	Create a backup copy of the old version of a patch as patch~.

--sort	Sort files by their name instead of preserving the original order.

--strip-trailing-whitespace
	Strip trailing whitespace at the end of lines.
