Functions
int	here_doc (char *limiter, int *in_out)
	Capture multiline input from stdin and write to a pipe readable from in_out[0] until a line containing only limiter is reached.
char **	get_paths (char **envp)
	Create a null-terminated, unique array of paths from the environment pointer envp. Trailing forward slashes included free of charge.
int	dispatcher (int n, char ***str_arrs, int *in_out)
	Dispatch n child processes with argument strings str_arrs[1][i], environment pointer str_arrs[2], where stdin for the first process is in_out[0] and stdout for the last process is in_out[1].
static void	_input (int argc, char **argv, int *is_here_doc, int *trunc_append)
	Check if in here_doc mode, verify arguments count accordingly, and set append or truncate accordingly.
