gnus-sum.el: Merge changes made in Gnus master

2012-07-09 Tassilo Horn <tassilo@member.fsf.org>
* gnus-sum.el (gnus-summary-limit-to-author): Use default value instead
  of initial input when reading the author to restrict the summary to.
2012-04-12 Lars Magne Ingebrigtsen <larsi@gnus.org>
* gnus-sum.el (gnus-select-newsgroup): Don't assume that the group
  buffer exists, which it doesn't if we haven't started Gnus.
