Way of bypassing all norm check (except line too long)

[matubu]

Describe the bug
Using a \ followed by a newline in the comment delimiter prevents the norminette from recognizing the end of the comment. Consequently, the norminette interprets the entire file as commented out.

Erroneous code

/* *\
/

#include <stdio.h>

int main() {
  for (int i=0; i<2;++i)
    printf("%d\n", i);
}

/**/

$ norminette test.c
test.c: OK!
$ gcc test.c 
$ ./a.out 
0
1

Additional infos

• OS: Ubuntu 22.04.1
• python3 --version: Python 3.10.12
• norminette -v: norminette 3.3.55

Additional context
You could also use a trigraph, making the issue harder to detect.

/* *??/
/

#include <stdio.h>

int main() {
  for (int i=0; i<2;++i)
    printf("%d\n", i);
}

/**/

Also, since the norminette never sees anything other than a comment, it does not check if the header is valid.
