This should work:

$ cat <<'EOF' >find-commit
#!/bin/sh
commit=$1; shift
for i in "$@"; do
  git rev-list $i | fgrep -q $commit && echo $i
done
EOF
$ sh find-commit full-40char-sha1-of-commit head1 head2 ...

You potentially end up traversing parts of the history multiple times
(if they are shared by multiple heads) but git is fast enough that
performance is fine.

I don't know of a way to do it all in a git command without the fgrep.
