M-x term has staircase effect, M-x shell hasn't

[clemens fischer]

hi.

i have used the terminal emulation in the past, but not the shell
command.  with the recent CVS emacs, things changed in that M-x term,
calling up bash(1) produces staircased output, as if only newline is
sent to the screen, but not carriage return.

  127 p3 # echo $TERM
                     eterm
                        ~
  127 p3 # echo $TERMCAP
                      
eterm:li#23:co#89:cl=\E[H\E[J:cd=\E[J:bs:am:xn:cm=\E[%i%d;%dH:nd=\E[C:up=\E[A:ce=\E[K:ho=\E[H:pt:al=\E[L:dl=\E[M:DL=\E[%dM:AL=\E[%dL:cs=\E[%i%d;%dr:sf=\n:te=\E[2J\E[?47l\E8:ti=\E7\E[?47h:dc=\E[P:DC=\E[%dP:IC=\E[%d@:im=\E[4h:ei=\E[4l:mi::so=\E[7m:se=\E[m:us=\E[4m:ue=\E[m:md=\E[1m:mr=\E[7m:me=\E[m:UP=\E[%dA:DO=\E[%dB:LE=\E[%dD:RI=\E[%dC
    ~

with M-x shell, things work as expected:

  0 p2 # echo $TERM
  emacs
  ~
  0 p2 # echo $TERMCAP
  emacs:co#90:tc=unknown:

the terminal emulation, including ANSI-term, produce the staircase,
but the shell doesn't.  sorry, but including the terminal
capabilities was the only thing i could think of, so please email me
if there's detail missing.  google did not turn up anything helpful
here.
