While working on this issue I discovered a second, related issue. The "old mode" field of diff files was always being read in as "0". This meant we were always working with bad data on the starting point of file permissions. I've attempted to fix this.

Also, I added a warning so when file permissions do not match "old mode" the user is told. Also, if "--force" is not used, the original file permissions are maintained.

Both fixes are in the attached patch.

(file #47508)

The following patch creates a file with mode 0644 and then changes the file mode from 0755 to 0644. Patch doesn't
recognize that the file has the wrong file mode and happily
applies the second patch as well; it should complain.

diff --git a/f b/f
new file mode 100644
index 0000000..257cc56
--- /dev/null
+++ b/f
@@ -0,0 +1 @@
+foo
diff --git a/f b/f
old mode 100755
new mode 100644
