That's it! For example, innfeed won't work correctly with incorrect
newsfeeds file, where   ,   and    \   appear in newsgroups' names.
The comma is not shell metacharacter, though. To be frank, i've got
a problem with special characters. One of my newsservers uses
large newsfeeds file, where each subscribed newsgroup is put into
this file for each outgoing feed.

Well, i think it's better to obey Usenet standarts.
I have removed some newsgroups from newsfeeds and now everything is ok.
