 Add noffle query option for checking all groups, if they are still
 available at the remote server(s) and delete them otherwise.
 
+In online mode, retrieve full article header from remote server if client
+sends a HEAD command. Presently, only the header lines from the overview
+are returned and the article is only retrieved on an ARTICLE or BODY command.
+The reason for this was that some readers (like pine) retrieve the group
+overview by sending lots of HEAD commands and their performance would badly
+suffer. On the other hand, some readers (like slrn) cache the header from
+a HEAD command, even if a following ARTICLE command gets more header lines,
+so that not all header lines are available when reading news in online mode,
+before the next start of the reader. But some header lines (e.g. Reply-To)
+are important.
+Maybe make the behaviour configurable.
