D7697: emit dirty signal for a directory on creation of a file even if the file is being watched individually

[Julian Wolff]

progwolff created this revision.
Restricted Application added a project: Frameworks.

REVISION SUMMARY
  KDirWatch emits a dirty signal for a watched directory when a file is ceated in this directory.
  However, currently this signal is not emitted when a file is added that is watched individually.
  With this patch, a dirty signal for the directory is sent even if a watched file is added.
  
  This fixes a bug in Okular.
  
  BUG: 384185
  
  See also the discussion in https://phabricator.kde.org/D7671

TEST PLAN
  Watched a directory and a file in this directory.
  Deleted and recreated the file.
  
  1. a "deleted" signal for the file is emitted
  2. a "dirty" signal for the directory is emitted
  3. a "created" signal for the file is emitted
  4. a "dirty" signal for the directory is emitted
  
  Tested only with inotify. There may be other places for other backends which need changes.
