New Revision: 231068
URL: http://svn.freebsd.org/changeset/base/231068

Log:
  MFC r230785:
  A debugger which requested PT_FOLLOW_FORK should get the notification
  about new child not only when doing PT_TO_SCX, but also for PT_CONTINUE.
  If TDB_FORK flag is set, always issue a stop, the same as is done for
  TDB_EXEC.
