Yes, but removing the entire block of code that handles short reads
causes many msvcrt tests to fail :-).

There is no general way to tell you're at the end of the file, before
you actually get there (by read() returning 0). But, you can't read
ahead, because that won't work for ttys. Suggestions?

While on the topic of reading, is there any reason why ReadFile()
calls ReadConsoleA() for console handles, but ReadFileEx() does not?
