Thanks!

So I started a git pull to get the latest master and as well a git reset 
--hard to assert that there are no modifications remaining.

Then I modified the file ui/x_keymap.c and called then the
git format-patch HEAD^

But I get 3 patches that are definitively not related to my changes:
erik@debian:~/qemu-test/qemu$ git format-patch HEAD^
0001-coroutine-Fix-setup-of-sigaltstack-coroutines.patch
0002-qcow2-Don-t-ignore-failure-to-clear-autoclear-flags.patch
0003-qemu-img-Fix-segmentation-fault.patch
erik@debian:~/qemu-test/qemu$

Using git diff shows my real changes...

So I created a patch file called keymap.patch but git format-patch HEAD^ 
just ignores it..

Maybe I missed something important...

Best regards,

Erik
