[pdftex] Blank lines are ignored when copying-and-pasting from PDF

Hi Reinhard,

Interesting workaround (attaching the key). The only problem I have with 
PDF attachments is that I want the PDF to work with all PDF readers. The 
PDF is an installation manual for my open source project and I want it 
to work even when the PDF reader does not support attachments.

I tried to insert spaces etc. but it seems that all spaces are removed. 
I have search the web quite intensively for a solution but haven't found 
one. You would think that this is problematic for others as well, for 
example when including source code snippets. I have tried the listings 
package (which is used for including source code) but it suffered from 
the same problem.


Kind regards,

Martijn Brinkers
