However, there is a bug recently introduced in the
merge-one-file script.  
Ok, if your patch below resolves the bug (please see my
other email just posted) please submit it.  (I'm hitting
this bug everytime there's a file deleted from the
kernel tree and I try to merge.)

Thanks,

Although the conflict resolution procedure I described applies
if you really had a real conflicting merge, I suspect your merge
should not have failed in the first place.

        case "${1:-.}${2:-.}${3:-.}" in
        #
        # Deleted in both or deleted in one and unchanged in the other
        #
        "$1.." | "$1.$1" | "$1$1.")
                if [ "$2" ]; then
                        echo "Removing $4"
                fi
                if test -f "$4"; then
                        rm -f -- "$4" &&
                        rmdir -p "$(expr "$4" : '\(.*\)/')" 2>/dev/null
                fi &&
                        exec git-update-index --remove -- "$4"
                ;;

The faliure code from "rmdir -p" leaks up and makes
git-update-index to be skipped.  Here is a fix.

[PATCH] merge-one-file fix

9ae2172aed289f2706a0e88288909fa47eddd7e7 used "rmdir -p"
carelessly, causing the "git-update-index --remove" to be
skipped.
