Your reading of fetchnews(8) is correct, but apparently this syntax is 
new to the NNTP update draft.  Both LIST ACTIVE and the wildmat format 
have not been formalized up until now.  I tried this against INN 2.3.4 
and it doesn't support comma-separated (or space separated) wildmat 
patterns (which really sucks).  For the time being, you'll have to use 
separate fetchnews commands rather than specifiying multiple wildmats in 
one command.  For example, instead of:

fetchnews -n -w "nl.test,nl.someother" news.myisp.nl


fetchnews -n -w "nl.test" news.myisp.nl
fetchnews -n -w "nl.someother" news.myisp.nl
