[issue12591] TextIOWrapper should fall back on read() if read1() doesn't exist

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

So, as the title indicates, I think we should make TextIOWrapper work with raw IO objects. The reason is so that write() can behave in a totally unbuffered way, which is necessary for Popen to behave appropriately.
