Well... it's only a *partial* solution (and perhaps you're already aware), 
but you can execute an arbitrary script after running git pull in a local 
working copy by creating a post-merge hook like this:

$ cat > .git/hooks/post-merge << EOF
heredoc> #!/bin/sh
heredoc> exec touch I-LIKE-TRAFFIC-LIGHTS.txt
heredoc> EOF

The problem, of course, is figuring out what to run instead of touch I-LIKE-
TRAFFIC-LIGHTS.txt, but it's a start...
