Bendikker's changes to gnu package entries

[Mikko Viinamäki]

Hi there! Directory user Bendikker has taken upon himself to add some things to 
all gnu package entries.

From the mouth of the horse:

Approved revision with such changes: https://directory.fsf.org/wiki/Gnucad

Do we like those changes or should those be removed? I think the intention is 
good but the effect might seem a bit spammy. Also, perhaps if wanted any such 
changes should come automagically with |Is GNU=Yes rather than by a hand job.
