cogito is phased out.

Just in case you want to get it in, here are some comments (made harder by 
the fact that you did not follow Documentation/SubmittingPatches)...

You might want to consider using format-patch next time ;-)

This can be be achieved by "git cat-file -t blob $sha1string^:$fname", and 
likewise for $sha1string.

+    exec meld .gitk_diffolder .gitk_diffnewer &

the temporary files...

Also, it would be nice to have it configurable which tool you use, a la 
git-mergetool.
