Review Comment:
I wanted to keep the logic the same as in the protobuf library (v4), they
have this code:
```
Edition getEdition() {
switch (proto.getSyntax()) {
case "editions":
return proto.getEdition();
case "proto3":
return Edition.EDITION_PROTO3;
default:
return Edition.EDITION_PROTO2;
}
}
```
In my tests the value of `syntax` was the empty string (not `proto2`) for
proto2 files, this is why it just compares against `editions` and `proto3`.
