[dired-collapse] does not update after collapsed file action (delete, rename, ...)

[zellerin]

Hello,

When you delete a collapsed tree (dired-flag-file-deletion and dired-do-flagged-delete), the deleted entry does not disappear from the dired listing. SImilar for rename.

Without collapsing mode - or when the entry is not collapsed item, it does disappear when deletion is done.

As a side note, I would think that it would be more intuitive to delete whole collapsed directory structure, not just the leaf, but I suppose this is a matter of preference.
