$input should return $cancel in some cases always.
e. g.: $input(?,e)
It returns all the time $null even if i click on cancel.
How should i make sure what button was clicked if the returning value is all the time the same?
Same for: $input(?,y) (which returns $true and $false but $yes and $no would be better in that case)
Also $input(?,n) returns on no also $false as it does on cancel.
For what are $yes, $no and $cancel if they aren't in use?
