Details:

Underscores and carets are displayed as "\_" and "\^", respectively, for
interpreter=='none'. Additionally a spurious output appears. Example:


axes
text(0.05, 0.5, 'foo_bar^foo', 'interpreter', 'none')


This produces the output "foo\_bar\^foo" instead of "foo_bar^foo". The
spurious output is


labels = 
{
  [1,1] = foo\_bar^foo
}
labels = 
{
  [1,1] = foo\_bar\^foo
}


The number of "labels" outputs depends on the number of carets and underscores
in the text string. The spurious output re-appears when the figure changes,
e.g. upon


title('foobar')


This bug is specific to graphics_toolkit 'gnuplot' and does not show for
graphics_toolkit 'fltk'.
