getpwent.c: isn't line supposed to be set NULL?

["Arvid E. Picciani" <aep@exys.org>]

the getpw* functions call getline in a dubious way
for example:

struct passwd *__getpwent_a(FILE *f, struct passwd *pw, char **line, 
size_t *size)
[..]
		if ((l=getline(line, size, f)) < 0) {
			free(*line);
			*line = 0;


is called from

struct passwd *fgetpwent(FILE *f)
[..]
	static char *line;
	return __getpwent_a(f, &pw, &line, &size);


where line is uninitialized.

first thing getdelim (forwarded from getline) does is:

if (!*s) *n=0;

so this looks wrong somewhere.
maybe i'm just missing an =0 in between.
