Theoretically, shouldn't be that difficult. The post-update hook fires 
on clone/update with the full path to the repo that got updated, e.g.

post-update-hook.sh /var/lib/public-inbox/lkml/git/7.git

Here's a quick and dirty start to the post-update-hook that I came up 
with:

-----
#!/bin/bash

topdir=$(echo $1 | sed 's|/git/[[:digit:]]*\.git$||g')
pidir=$(basename $topdir)
url="http://localhost:8080/${pidir}"

cd $topdir/..

if [[ ! -f $pidir/msgmap.sqlite3 ]]; then
    listid=$(git --git-dir=$1 show master:m | grep -i '^List-Id:' | sed 's|.*:.*<\(.*\)>$|\1|g')
    email=$(echo $listid | sed 's|\.|@|')
    public-inbox-init -V2 $pidir $pidir/ $url $email
    # Need logic here for adding to the config file
fi

public-inbox-index $pidir
-----

It needs some kind of a template entry for adding to the config file 
post-init, but this should at least do the right thing for running 
public-inbox-index on repo updates.
