Details:

Originally reported on the mailing list. [1]
When adding strings to plots, any "tab" characters are ignored and a warning
is displayed.
Example:

clf;
axes ();
var=456;
str= sprintf ('Signal\t\tMaxFreq\nnextline\t%d', var);
annotation ('textbox', ...
  [0.15 0.65 0.3 0.15], ...
  'String', {str}, ...
  'FontSize', 14, ...
  'FontName', 'Arial', ...
  'LineStyle', '--', ...
  'EdgeColor', [1 1 0], ...
  'LineWidth', 2, ...
  'BackgroundColor', [0.9  0.9 0.9], ...
  'Color', [0.84 0.16 0]);


I'll push a patch as soon as I have a bug number.
