Add an option to disable automatic parenthesis insertion

Currently, when entering a function using TAB auto completion, a parenthesis is automatically added.

For me this is very confusing as I'm used to type parentheses myself (on German keyboards this may be simpler than on US-English keyboards as with German keyboards parentheses are available via SHIFT+8 to 9):

Can you please add an option to PowerShell so that auto completion does not add an opening parenthesis?
