Summary: GHCi breaks the terminal

Initial Comment:
After running ghci the terminal does not work exactly
as it should: Running "su" does no longer work for some
unknown reason (su stops after reading the first
character of the password). This happens with ghc 5.04
as well as 6.0 and current CVS-version, both in xterm
and console. This only seem to be a problem with my
Linux/Debian installation, I cannot reproduce the
problem on Solaris.

Also some minor spelling :) According to the CVS
users-guide the reverse of -frules-off is the very same
-frules-off.

The (only) difference is that instead of icanon (before)
ghci leaves the terminal with -icanon (su no longer works
using line buffering, I think).

I've had this problem before with an older installation of
Debian too but no one else of my Debian-running friends seem
to have this problem.

Well, it's a minor problem but annoying.

I can't reproduce this on our boxes here.  It could be a 
readline problem.

Could you try 'stty -a' before and after running GHCi, and 
post the results?
