docs: names longer than 175 bytes (not 176) are stored in longnames

Quoting fusefrontend_reverse/node_helpers.go :

	// File names are padded to 16-byte multiples, encrypted and
	// base64-encoded. We can encode at most 176 bytes to stay below the 255
	// bytes limit:
	// * base64(176 bytes) = 235 bytes
	// * base64(192 bytes) = 256 bytes (over 255!)
	// But the PKCS#7 padding is at least one byte. This means we can only use
	// 175 bytes for the file name.
