legend.m: Text objects should inherit textcolor, interpreter properties from legend (bug #40064). * scripts/plot/legend.m: Match variable names in function prototype to docstring. Get textcolor and interpreter properties from legend axis object and apply them when creating text objects. Use '~' to ignore dummy input to callback functions. Remove some for loops for performance.

# Like mv $1 $2, but if the files are the same, just delete $1.
# Status is 0 if $2 is changed, 1 otherwise.

if test -r $2; then
  if cmp $1 $2 > /dev/null; then
    echo $2 is unchanged
    rm -f $1
