[Bug-ed] 'ed' display

[Maurício]

Hi,

After I use a terminal for some time, entering 'ed' and typing a
few special characters gives me unexpected display. For instance,
if I type something and then backspace, I get this:

  error^J^J

Seems mostly a display problem, as the result is usually what
I want. My solution to this is to open a terminal just for using
'ed'. This way, I never get this problem. However, I wasn't
able to figure out exactly what can cause it. Usually, I use a
combination of standard unix tools (sed, cat etc.), less (as
pager) and compilers (gcc, ghc). Most of the time I use tools like
'ed' with 'rlwrap', but not always, and that doesn't change the
problem.

I use bash and mlterm on latest ubuntu. 'ed' is version 1.4
(installed on /usr/local, as ubuntu still has 'ed' 0.7).

Thanks,
Maurício
