Subject: [PATCH] wordexp.3: SYNOPSIS: Use 'restrict' in prototypes

Both POSIX and glibc use 'restrict' in wordexp().
Let's use it here too.

.../glibc$ grep_glibc_prototype wordexp
posix/wordexp.h:62:
extern int wordexp (const char *__restrict __words,
		    wordexp_t *__restrict __pwordexp, int __flags);
.../glibc$
