Hi!
I've face a bug during execution of combinediff. Let's say I have following first and second patch files:
first.patch

--- a/file.c
+++ b/file.c
@@ -0,0 +1,3 @@
+a
+b
+c

second.patch

--- a/file.c
+++ b/file.c
@@ -1,3 +1,2 @@
 a
 b
-c

After executing combinediff -p1 first.patch second.patch I get the following output:

diff -u b/file.c b/file.c
--- b/file.c
+++ b/file.c
@@ -0,0 +1,2 @@
+a
+b

As you see, the path to the first file is b instead of a. I understand that it doesn't affect patch applying, but it breaks the convention used by almost all package vendors. Hope you would have a chance to fix it. Thanks in advance!
