Hi, Gerald.
This can't even happen. spec if filtered later with:
---
case THREECHARMONTH:
case FULLMONTH:
case THREECHARDAY:
case FULLDAY:
---
So no default case here.
Even if the default case cannot be reached, it is not a 'bad thing' to
have one, even if it is an error message stating "Something went wrong,
we should not get here" with an exit code...
Why? There's no default case, treat is as 'if () {} else if () {} etc.'.
It's the same thing to have explicit initializers for all local
variables even if I don't use it before
set some value. It's a pollution, especially if used to silence analyzer
warnings.
