strcat.3: SYNOPSIS: Use 'restrict' in prototypes 

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

.../glibc$ grep_glibc_prototype strcat
string/string.h:133:
extern char *strcat (char *__restrict __dest, const char *__restrict __src)
     __THROW __nonnull ((1, 2));
.../glibc$ grep_glibc_prototype strncat
string/string.h:136:
extern char *strncat (char *__restrict __dest, const char *__restrict __src,
		      size_t __n) __THROW __nonnull ((1, 2));
.../glibc$
