I wondered if this (and the other one) want to be in test-lib but I
am on the fence.  All three tests that call this helper in t0001 are
protected with MINGW prerequisite, but until I realized it, the call
to "attrib" (whether it is given as a full path or relies on $PATH
lookup) looked like a portability nightmare waiting to happen.  It
would make it even worse if we moved the above as-is to test-lib, as
it is harder to see what the callers are doing once we did so.

With a change like this, however

	is_hidden () {
		if ! test_have_prereq MINGW
		then
			BUG "use of is_hidden outside MINGW prerequisite"
		fi
		case "$("$SYSTEMROOT"/system32/attrib "$1")" in 
		*H*?:*)	return 0 ;;
		*)	return 1 ;;
		esac
	}

I think it is OK to consolidate these two copies into one in test-lib

Thanks.
