OK, please let me descript what I have done step by step.

1. emacs -q
2. M-x eshell
3. ls
4. ls
5. do 'ls' to list the files, until the prompt reachs the bottom
6. ls, then the prompt will scroll to the half of a page. I think it  
should be still stayed at the bottom.

If you do 'ls' in a path where has lots of files and can not be displayed  
in one page, the prompt will
appear in the half of the page directly, instead of the bottom of the page.

Is it a intended behavior? If yes, how to disable the feature?

I asked this (a intended behavior?), because if I do the following:
1.  emacs -q
2. C-x C-f
3. then hit 'enter', 'enter'..... in the keyboard
it will do the same behavior as in eshell (scroll to the half of a page).

But after I set following in .emacs, it can scroll line by line.

  '(scroll-conservatively 10000)
  '(scroll-down-aggressively 0.01)
  '(scroll-margin 3)
  '(scroll-preserve-screen-position t)
  '(scroll-up-aggressively 0.01)

But the above settings did not effect the 'eshell'. And I could not get  
help from *info* or the web
(http://www.gnu.org/software/emacs/manual/html_node/eshell/Smart-scrolling.html),  
they are
empty.

At last, let me make clear my request, that is: how to scroll line by line  
in eshell?

Thanks in advance!
