write_url with local subdirectory

[jmcnamara]

Reported by Frederic Sievert.

When I use write_url method to open an external excel sheet which is located in a subfolder of current directory, Excel cannot open the file stored by hyperlink.

In other words, I want to use the relative path feature.

Example of usage which fails :

$worksheet-> >write_url( 'C2', 'external:other/Italy.xlsx', $ire_url_format) 

or

$worksheet-> >write_url( 'D2', 'external:./other/Italy.xlsx', $ire_url_format)

This kind of url works with Spreadsheet::WriteExcel.
