[cogito] cg-merge does not remove files removed upstream on fast-forward

[Blaisorblade <blaisorblade@yahoo.it>]

Once again, (not the first time) when doing "cg-merge origin" (or cg-update I 
guess, too) I find a tons of files which were removed upstream and cogito 
didn't remove. It was a fast-forward merge on Linus' tree:

$ cg merge origin
Fast-forwarding d83c671fb7023f69a9582e622d01525054f23b66 -> 
a52e8381c430896d3bd6065a34fda99cb5c74c82
        on top of d83c671fb7023f69a9582e622d01525054f23b66...

cg version
cogito-0.15.1 (b07f98ba4cabdd9d208da28be932e547675e5cdf)
(The base id is ab91bd11258f8987fc8d537871c733e04f8c8248, I've added a trivial 
patch to add more options to cg-diff and cg-mkpatch, i.e. unrelated).

Below there is the excerpt of code in tree_timewarp:

       # Kill gone files
        git-diff-tree -z -r $base $branch | xargs -0 bash -c '
                while [ "$1" ]; do
                        header="$1"; shift
                        file="$1"; shift

                        # match ":100755 000000 14d43b1abf... 000000000... D"
                        if echo "$header" | egrep "^:([^ ][^ ]* ){4}D" 
>/dev/null; then
                                rm -- "$file"
                        fi
                done
        ' padding

I must say I also saw git-ls-files --deleted running with top (probably from 
cg-patch), but it didn't seem to help.
