when you set borders around fusioned cells in excel they are not displayed correctly by the dump function

Version used : 2.21

when you drow borders around cells that are fusioned in
excel, they are not displayed as it should.
Sample step to reproduce : in excel, take a rectangle of 2x3 cells,
write a text in this fusion, set a border around this fusion.

Solution (the number on the left is the line number in
excel_reader2.php) :
445:    // Borders
446:    $bLeft = $this->borderLeft($row,$col,$sheet);
447:    $bRight = $this->borderRight($row,$col,$sheet);
448:    $bTop = $this->borderTop($row,$col,$sheet);
449:    $bBottom = $this->borderBottom($row,$col,$sheet);
450:    $rowspan = $this->rowspan($row,$col,$sheet);
+       $colspan = $this->colspan($row,$col,$sheet);
+       if ($rowspan>1) { $bBottom=$this->borderBottom($row+$rowspan-1,$col+
$colspan-1,$sheet); }
+       if ($colspan>1) { $bRight=$this->borderRight($row+$rowspan-1,$col+
$colspan-1,$sheet); }
451:    $bLeftCol = $this->borderLeftColor($row,$col,$sheet);
452:    $bRightCol = $this->borderRightColor($row,$col,$sheet);
453:    $bTopCol = $this->borderTopColor($row,$col,$sheet);
454:    $bBottomCol = $this->borderBottomColor($row,$col,$sheet);

Start in excel_reader2.php around lines 445-454, where the dump function reads borders for merged cells. Reproduce the issue with a bordered 2x3 merged range in Excel and compare the dumped borders with the proposed row and column span handling. Done means the merged range displays its right and bottom borders correctly.
