redundant check of msg in does_not_exist_skipping

Hi,
I was looking at commit aca992040951c7665f1701cd25d48808eda7a809

I think the check of msg after the switch statement is not necessary. The
variable msg is used afterward.
If there is (potential) missing case in switch statement, the compiler
would warn.

How about removing the check ?

Thanks
