4 chars tells me that something put the tty in raw mode, but didn't
update the VMIN value (which is shared with VEOF in cooked mode, which
is ctrl-D (i.e. 4) normally). Normally VMIN is put at 1 so that the
app gets each keystroke immediately. What happens if you type

stty eof '^a'

before starting vi?


Anyway, I use vim, and that works wonderfully.
