xover header filtering (From:, Subject:, Message-ID:, etc.) won't work.
xover_filter expect scope_header matches xover field name. in src/acc.c, while
reading filter file and assigning header name to scope_header, colon (":") in
header name has stripped off.
As xover field name has colon, they won't match.
Fix: Following patch should fix this.
How-To-Repeat: put "filter" permission and filter file name to nntpcache.access, put
some "Header:" filter in filter file and see if it work.
I should have said that the version of nntpcache is 3.0.1 (latest
version in the ports).
