Upgrade to 1.11.2:

* Fix segfault when timeout or connection reset encountered while
  article header is read.

* fetchnews will no longer re-fetch the active file for a server if it
  has been completely received even if fetching articles from this server
  encounters a problem.  Long-standing bug.  Debian bug #70052.

* fetchnews will now properly mark the active for complete re-fetch if
  it says so. Previously, it forgot the mark in some circumstances.  A
  problem fetching the active file or descriptions for a newly added
  server will now mark the active for re-fetch even if articles have
  successfully been retrieved from the same server.

* Fix use-after-free segfault when server dies while body is being
  received.

* Support quoted strings on the right hand side of configuration lines.

* Support IPv6 in fetchnews as well.

* In LIST ACTIVE/GROUP, keep group interesting in spite of being
  pseudo (which includes empty) as long as it is interesting. Avoids
  unsubscription of low-traffic groups that fall empty.
