pdfjoin loses web links in the PDFs

[Gary Dale]

This is frustrating. I'm running Debian/Buster (AMD64) and just finished 
creating web links (mostly mailto:<e-mail address> in a two-part 
directory I created using Scribus. I exported the files to PDF on a 
Debian/Stretch machine because Buster uses a version of Ghostscript that 
breaks the PDF export in Scribus (they recently broke it on Stretch as 
well, but I put the older Ghostscript 9.20 version on hold so I can 
still use Scribus).

The PDF files I created worked fine individually but when I tried to 
merge them into a single PDF, the web links are lost. I'm not sure if 
this a limitation of pdfjoin or a bug in the current implementation.
