`insert_void` not working for functions returning a pointer

[younesaassila]

Works fine for functions returning normal type:

Before:

char test(){}

After:

char    test(void)
{
}

---

Doesn't work for functions returning a pointer:

Before:

char *test(){}

After:

char    *test()
{
}

Expected:

char    *test(void)
{
}

---

Fix: Edit regexp to work for function declarations with any number of * characters between type and function name
