It turns out that the termios hook is not called if the program uses
buffered stdio functions like `getc' and `getchar'.  DJ, is this
intentional, or simply an oversight?

It seems like the call to the hook was left inside `read' and `write'
when we pushed the CR-LF -> NL conversion into the higher level,
leaving `_filbuf' and `_flsbuf' to call `_read' and `_write' directly,
even for text files.

Mark, does this mean that Bash never uses any buffered stdio functions, 
only `read' and `write' for its interactive I/O?  Otherwise, I don't 
understand how does the new port manage to invoke termios.

Anyway, this seems like a bug that should be corrected.  The simplest
way is to call the hook inside `_flsbuf' and `_filbuf'.
