I'm not in favor of this change, as a number of alternatives were
suggested in the thread you cite (Gmane:
http://thread.gmane.org/gmane.comp.version-control.git/150141).

A few hints, just in case you deploy this code:

> +	if ((global_path == NULL || access(global_path, X_OK) > 0) &&
> +			access(local_path, X_OK) > 0)
> +		return 0;

access(2) returns zero on success, negative on failure.

> +	if (global_path != NULL)
> +		ret = run_hook_file(global_path, index_file, argv) ||
> +			run_hook_file(local_path, index_file, argv);

What is the value of ret if the hook in global_path fails? Is it the exit
code, or is it 1? What should it be?
