Well. Yes, this I'm looking for! :-)

Why not document this nice function in help and command reference? I 
found only "monotone log" or "monotone log /id/", with /id/ should be a 
revision. I never try to use a file instand a /id/.

With previous command it's easy to make a script. Here are two of them.

>>> cut here >>>
filename="MyPath/MyFile"
rev2=""
monotone log $filename | \
sed -n -r -e 's/^Revision: ([0-9a-f]{40})$/\1/p' | \
while read rev1; do
  if [ -n "$rev2" ]; then
    echo "diff $filename"
    echo "# Revision: $rev2"
    echo "# Ancestor: $rev1"
    monotone diff --revision="$rev1" --revision="$rev2" $filename
  fi
  rev2=$rev1
done
<<< end cut <<<


>>> cut sample with log entries >>>
filename="MyPath/MyFile"
rev2=""
monotone log $filename | \
while read line; do
  rev1=`echo "$line" | sed -n -r -e 's/Revision: ([0-9a-f]{40})/\1/p'`
  if [ -n "$rev1" ]; then
    if [ -n "$rev2" ]; then
      echo "diff $filename"
      monotone diff --revision="$rev1" --revision="$rev2" $filename
      echo "# ====================================================="
    fi
    rev2=$rev1
  fi
  echo "# $line"
done
<<< end cut <<<

No X installed on all places. Some Windows. :-(

But I need no monotone-viz now, have "monotone log <file>" now!
Many thanks for support!
