Hi!

Just a question.  Why would you have code for handling NULL?  strdup(3) doesn't handle it.

```c
$ grepc strdup .
./include/string.h:char *strdup (const char *);
./src/string/strdup.c:char *strdup(const char *s)
{
	size_t l = strlen(s);
	char *d = malloc(l+1);
	if (!d) return NULL;
	return memcpy(d, s, l+1);
}
```
