# Usage: svn-annotate file [start-line [end-line]]
# Will output svn annotate on file + line numbers
# eventually cut depending on the given lines
function svn-annotate() {
  # Work on a tempfile to avoid broken pipe
  f=$(tempfile)
  svn annotate "$1" > $f
  CAT="cat -n" # Integrate line numbers, just remove the "-n" to disable
  if [ "$2" == "" ]; then
    # No start or end line
    $CAT $f
  else
    if [ "$3" == "" ]; then
      # Only start line
      $CAT $f | tail -n $2
    else
      # Start and end line
      $CAT $f | head -n $3 | tail -n $(($3-$2+1))
    fi
  fi
  # Cleanup before leaving
  rm -f $f
