Thanks to all.
With interpret-trailers has been easy to make a simple script, also it
checks if the Hash passed is a valid Object.
I haven't found a simple way to mantain the blank line above the
output of interpet-trailers (not even through cleanup).
Follows the script, maybe could be usefull for somebody:

#!/bin/sh
for i in $*
do
    git show $i &> /dev/null
    if [ $? = 0 ]
    then
        trailers+=" see-also=$i"
    fi
done

msg=$(cat /dev/null | ../git-interpret-trailers $trailers)

git commit -m "$msg" -e
