[PATCH 14/17] wcstok.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar]

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

.../glibc$ grep_glibc_prototype wcstok
wcsmbs/wchar.h:217:
extern wchar_t *wcstok (wchar_t *__restrict __s,
			const wchar_t *__restrict __delim,
			wchar_t **__restrict __ptr) __THROW;
.../glibc$
