Đoàn Trần Công Danh 04b9978a29 srcpkgs/w*: convert patches to -Np1
* wine is kept at -Np0

```sh
git grep -l '^patch_args=-Np0' "srcpkgs/$1*/template" |
while read template; do
	for p in ${template%/template}/patches/*; do
		sed -i '
			\,^[+-][+-][+-] /dev/null,b
			/^[*-]\+ [0-9]\+\(,[0-9]\+\)\? [*-]\+$/b
			s,^[*][*][*] ,&a/,

			}
			/^+++ -/{

				b
			}
			s,\(^+++ \)\(./\)*,\1b/,
		' "$p"
	done
	sed -i '/^patch_args=/d' $template
done
