I think new feature like this should be postponed after 1.5.4 is out;
we are now in feature freeze (only bugfixes are accepted).

That said, does git-showrel solution proposed by  Johannes Schindelin
in
  Message-ID: <Pine.LNX.4.64.0712182250040.23902@racer.site>
  http://permalink.gmane.org/gmane.comp.version-control.git/68840
work for you?

Below version of git-showrel script which uses proposed 'commit:./relpath'
syntax (it could be improved, of course):

cat > git-showrel <<\EOF
#!/bin/sh

rel=$(git rev-parse --show-prefix 2>/dev/null)
git show $(echo "$@" | sed -e "s!:./!:${rel}!")

EOF
