Sorry, I had told git send-email to use [PATCH v2]. *shrug*

The value of the messages is debatable. Feel free to discuss.

This gives such an error using ffmpeg command line with this patch:
...
[xcbgrab indev @ 0xa156740] Cannot get xcb pointer
:1: Input/output error
The last line may suffice.

Thanks,
