Re: [PATCH v3 0/4] MR4377: Reimplement msvcrt env functions to match native.

[eric pouech (＠epo)]

in first patch, when copying existing env, instead of

```plaintext
size = p - cur_env + 1024;
env = malloc( size * sizeof(*env) );
ok( env != NULL, "malloc returned NULL\n" );
for (p = cur_env, q = env; *p; p += wcslen( p ) + 1)
{
    wcscpy(q, p);
    q += wcslen( q ) + 1;
}
```

you could do

```plaintext
size = p - cur_env;
env = malloc( (size + 1024) * sizeof(*env) );
ok( env != NULL, "malloc returned NULL\n" );
memcpy( env, cur_env, size * sizeof(*env) );
q = env + size;
```

(not modifying myself the serie to avoid double write until you're done)
