-	Fix to use MacOS legacy font support by Masatake Yamato,
-	on Mac OS X. It is not working since 2.3.5. In FT_Open_New(),
-	if FT_New_Stream() cannot mmap() specified file and cannot
-	seek to head of specified file, it returns NULL stream
-	and FT_Open_New() returns the error immediately. On MacOS,
-	most legacy MacOS font falls into such scenario because
-	their data forks are zero-sized and cannot seek. To proceed
-	to guessing of resource fork fonts, the functions for legacy
-	MacOS font must lay by NULL stream returned by FT_New_Stream().
-
-	* src/base/ftobjs.c (IsMacBinary): Returns an error
-	FT_Err_Invalid_Stream_Operation immediately when NULL stream
-	is passed.
-
-	(FT_Open_Face): Even when FT_New_Stream() returns an error,
-	proceed to fallback. Originally, legacy MacOS font is tested
-	in the cases of FT_Err_Invalid_Stream_Operation (occurs when
-	data fork is empty) or FT_Err_Unknown_File_Format (occurs when
-	AppleSingle header or .dfont header is combined).
-	Now the case of FT_Err_Cannot_Open_Stream is included.
-
-	* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream
-	is NULL, skipping FT_Stream_Seek() to the head of stream
-	and proceed to unit testing of raccess_guess_XXX().
-	FT_Stream_Seek() for NULL stream causes Bus error on Mac OS X.
-
-	(raccess_guess_apple_double): Returns FT_Err_Cannot_Open_Stream
+	Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is

+	cannot mmap() the specified file and cannot seek to head of the

+	a scenario because their data forks are zero-sized and cannot be
+	sought.  To proceed to guessing of resource fork fonts, the
+	functions for legacy MacOS font must properly handle the NULL stream
+	returned by FT_New_Stream().
+
+	* src/base/ftobjs.c (IsMacBinary): Return error
+	FT_Err_Invalid_Stream_Operation immediately when NULL stream is

+	skip FT_Stream_Seek(), which seeks to the head of stream, and
+	proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()
+	for a NULL stream causes a Bus error on Mac OS X.
+	(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
 	immediately if passed stream is NULL.
-
 	(raccess_guess_apple_single): Ditto.
