In 99 out of 100 cases this is the correct behavior - to support unix
"raw" mode semantics, the server must **temporarily** enter passall
mode.  Since servers are not hard-wired terminal, there may be a few
cases where this doesn't give the intended result, but you break a
lot more stuff by not having it be the **default** behavior.

Please consider carefully before bitching about this, it's been broken
before (some 3.x releases) and took a long time to get it right again.

If the login behavior causes you distress, then what you really want
is /etc/ttys control of raw vs cbreak vs cooked mode for the prompt,
not LAT changes.
