git doesn't support stat info with plain --format, which is shame :( but it's easy to script it away, here's my quick and dirty solution, should be quite readable:

#!/bin/bash

format_log_entry ()
{
    read commit
    read date
    read summary
    local statnum=0
    local add=0
    local rem=0
    while true; do
        read statline
        if [ -z "$statline" ]; then break; fi
        ((statnum += 1))
        ((add += $(echo $statline | cut -d' ' -f1)))
        ((rem += $(echo $statline | cut -d' ' -f2)))
    done
    if [ -n "$commit" ]; then
        echo "$commit;$date;$summary;$statnum;$add;$rem"
    else
        exit 0
    fi
}

while true; do
    format_log_entry
done

I'm sure, that it can be scripted better, but hey - it's both quick AND dirty ;)

usage:

$ git log --pretty=format:"%h%n%ai%n%s" --numstat | ./script

Please note, that format, that you specified is not bulletproof. Semicolon can appear in commit summary, which will break number of fields in such line - you can either move summary to end of line or escape it somehow - how do you want to do it?
