Hi! all emacs hackers!

I have been using emacs about one and a half year. (it is first time to send
an email)

However, I met inconvenient behaviors in eshell & hl-mode

1) eshell (ntemacs)

  : eshell (pseudo shell?) seems to be buffering at all times

  (ex) a. run "python" -> not display ">>" and not get my inputs
           (I know "python -u" is working but ..)

       b. run "ftp" same as above

       c. interacting more & less like terminal related tools

     => I want eshell works same as real shell with all eshell's specialized
functions

2) hl-mode (emacs in linux also)

  : when I turn on (hl-line-mode &optional arg) in hl-line.el,
    emacs don't display highlighed overlay at the end of buffers
    but display partial part of whole one line

  : it seems to display from start of line to (point-max)

    => I want that current line is highlighted all the time!!

Help me to solve these problems in my emacs life!

I want to do myself and spend my time if you just advise me!
  (or if you know how to solve and inform me! thank you so much)

Thank you for taking your time to read!
