[PATCH 12/23] putgrent.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar <alx.manpages@gmail.com>]

glibc uses 'restrict' in putgrent().
Let's use it here too.

.../glibc$ grep_glibc_prototype putgrent
grp/grp.h:93:
extern int putgrent (const struct group *__restrict __p,
		     FILE *__restrict __f);
.../glibc$
