Package: patchutils
Severity: normal
Version: 0.3.2-2
The attatched patch is a reduced version (the original was massive) of a
patch generated from git. When trying to feed it to interdiff I get
errors like:
root@debian:/# interdiff test2.diff test2.diff
The next patch would create the file /tmp/interdiff-1.QMmyg0,
which already exists! Assume -R? [n]
In the middle of the file are the following two lines:
diff --git a/arch/arm/mach-bcm2708/bcm2708.h
b/arch/arm/mach-bcm2708/bcm2708.h
new file mode 100644
Which as I understand the patch format do not form a part of the actual
patch and should be ignored by toools.
However if I remove either of these two lines then interdiff accepts the
patch without errors.
Any idea what is going on?
