Set single-click action in Dolphin also removes "Delete" from context menu

[Bill777]

This in 13 Maya KDE, 32bits.

Setting single-click action in Dolphin via the Settings - configure Dolphin - Navigation panel
also removes "Delete" from context menu
and adds a garbage line to /home/mint/.kde/share/config/kdeglobals

The result was to add these lines to /home/mint/.kde/share/config/kdeglobals
    [KDE]
    ShowDeleteCommand=false
    Single=Click=true
    SingleClick=true

The correct addition/amendment would be merely
    [KDE]
    SingleClick=true

The option to remove Delete from the Dolphin context menu, should one feel the pressing need, properly lies in
Dolphin, Settings - Configure Dolphin - panel General - tab Context Menu.

Others might consider this bloat and wonder why it is there.
Maybe someone out there finds it essential to day-to-day administration.

Also see bug 927372, something which is reported several times in the forum but not addedtothe bugreport, where the single-click setting randomly comes unstuck.
A deliberate re-setting to double-click is probably happening elsewhere, somewhere, in Maya.

I see a further issue here. How is it that this kind of thing gets through, and who was responsible? Who should be responsible?
I might suspect that it was not an accident, but an act of deliberate & resentful insurgency, perhaps by individual(s) whose background o/s uses double-clicks as a matter of habit. That kind of behaviour, and that it can be implemented in a release, is a matter for general concern.(IMO)

For further discussion: Single-click seems to have been the KDE standard, and I feel that is what should be default in Mint, if only for the avoidance of RSI. Others may wish to retain old habits.
(I wouldn't want to alter that single-handedly, it might seem like sabotage.)
