Re: MERGE_RR droppings

git mergetool decides to use rerere-remaining based on the existence of the .git/MERGE_RR file:

    if test -e "$GIT_DIR/MERGE_RR"
    then
        files=$(git rerere remaining)
    else
        files=$(git ls-files -u | sed -e 's/^[^ ]*      //' | sort -u)
    fi

But when I disabled rerere, I still had MERGE_RR files left over in my .git directory. This causes git-mergetool to do the wrong thing.

I do not know if the correct fix for this is to check rerere.enabled instead.

Is MERGE_RR leaking somewhere it should have been cleaned up? I often see leftover MERGE_RR files even though I am certain the project is not in the middle of a merge.

Is this a bad semaphore to check? I do not see it being used this way anywhere else.
