James I just saw that I posted this patch on 9th already, but todays git pull from your tree didn't show the inclusion of this one (and another patch posted the same day). Event though it's reported in your summary from the 26 ! If I'm to quick then I'm sorry for sending it twice, if there's any other reason for this patch to not be included please let me know.
