Fix &rt; to > in mail (in rename status line)

fixes #1104

Indeed the HTML entity for > is >, not "&rt;" which is not an existing HTML entity (for the record: the angle brackets < and > entities are < and > which stand for "less than" and "greater than", not the hypothetical "< and &rt;" that I suppose one could type thinking to "left" and "right" since e.g. « and » are « and » which stand for "left angle quote" and "right angle quote"...).

Thanks for the fix.
