It doesn't.

There are two solutions:

1) Add it to WinHugs, easy enough, just make the typed character
handler also write a character (currently it deliberately blocks it).
This won't fix it in command line hugs.

2) Add it to Hugs, on windows platform explicitly do a getchar,
putchar. WinHugs would receive this fix automatically because it traps
putchar.

As for line buffering, this should be something specified by the
standard. Lines can be buffered with a unlines . map (reverse .
reverse) . lines style construct, and this was how I was taught to use
interact with buffering.
