Sync with delete - should it clear empty dirs?

[themagic314]

After using the sync task with "delete": true, empty nested folders are not removed when the last file is deleted.
Users can solve this by using an additional task with a command like find /dir/ -empty -type d -delete after sync.

The question is whether this is intended behavior or sync should perform a "full" sync, including deleting empty directories.

This is not really intentional however, from what I recall rsync won't delete such directories either unless --prune-empty-dirs is set. This is possible to implement, but I'm not sure if making it part of "delete": true is a good idea. For example, this may prevent creating empty nested folder by sync command

Latest 0.14.2 has the fix to remove the remote directory if no such directory on the local side (if delete is true)

[umputun]

note: another nice side-effect of this fix - the delete command in non-recursive mode refused to remove an empty directory. Now it will, but only if the directory is empty. To remove non-empty directories recursive flag should be used, as before
