POSIX uses 'restrict' in posix_spawnp().
However, glibc doesn't.
Let's document here the more restrictive of them, which is POSIX.
I reported a bug to glibc about this.
$ man 3p posix_spawnp |sed -n '/^SYNOPSIS/,/;/p'
SYNOPSIS
#include <spawn.h>
int posix_spawnp(pid_t *restrict pid, const char *restrict file,
const posix_spawn_file_actions_t *file_actions,
const posix_spawnattr_t *restrict attrp,
char *const argv[restrict], char *const envp[restrict]);

__nonnull ((2, 5));

I conciously did an exception with respect to the right margin
of the rendered page. Instead of having the right margin at 78
as usual (per Branden's recommendation), I let it use col 79
this time, to avoid breaking the prototype in an ugly way,
or shifting all of the parameters to the left, unaligned with
respect to the function parentheses.
