I've noticed that if I execute cppfront.exe with the -import-std option on a .h file that doesn't contain any cpp2 code, then an #endif will be missing at the end of the file.

This file:
color.h2

enum Color: uint8_t {
 None = 0,
 Black = 1,
 White = 2,
};

With the command below:

cppfront -cwd ./generate ../src/color.h2 -import-std

Gerenates the following cpp1 code with a missing #endif:

#ifndef COLOR_H_CPP2
#define COLOR_H_CPP2
#define CPP2_IMPORT_STD Yes
#include "cpp2util.h"
enum Color: uint8_t {
 None = 0,
 Black = 1,
 White = 2,
};

@JohelEGP I think the PR #1319 fixes exactly this bug.
Do you see a cleaner way to fix this bug?
