Log Message:
make(1): properly initialize For structure in For_Eval

Initializing a Buffer or a strlist_t with zero-valued bytes only works
by conincidence, but because it would be the correct way.  In the code
path "missing `in' in for", that zero-filled Buffer is freed using
Buf_Destroy, which could have invoked undefined behavior.
