Error while defining enum comments

[fahernandez]

Steps to reproduce the issue

Steps

1. Define an enum proto message with comments containing a .

// DeepEnum is one or zero.
enum DeepEnum {
    // FALSE is false.
    FALSE = 0;
   // TRUE is true.
   TRUE = 1;
}

// DeepEnum comment.<--This dot
DeepEnum ok = 3 [(grpc.gateway.protoc_gen_swagger.options.openapiv2_field) = {description: "DeepEnum description."}];

2. Generate the swagger documentation.

Expected behavior

1. The swagger code is generated without errors

Actual behavior

1. An error code is triggered.

Hipotesis
This error is triggered by an error on protoc-gen-swagger/genswagger/template.go:1268. The solution is to refactor the if behavior.

If you remove the dot from the comment it will generate the swagger code without errors.

What does the generated swagger look like? Would you like to contribute a fix for this?

[fahernandez]

The swagger file is not generated due the error code. Sure, I will fix it.
