Well it's not that hard. You can try this:
=====================
#!/bin/bash
FOREIGNSRC=$1
DIFFCMD="diff -ubdr -x \"*.hg*\" . $FOREIGNSRC"

NODES=$( hg log --template "{node} ")
for node in $NODES; do
      hg up -C $node > /dev/null
      diffcount=$($DIFFCMD | wc -l)
      echo $diffcount $node
      # $DIFFCMD
done  | sort -n | head
=====================
which shows you the ten most propable candidates.

Have a nice day,
