Started working on list scan on the &comments string.
For now the comments are extracted successfully, however the join() works weird.

While regex extracts every non-multiline comment as it should, join(matchlist()) does not return joined list of matches (duh).

comments: s1:/*,mb:*,ex:*/,://,b:#,:%,:XCOMM,n:>,fb:-
matches (simulated on virex): //,#,%,XCOMM,>
joined (from debug info): //q,qqqqqqqq
