bug#5375: 23.1.91; eshell eshell-cmpl-load-hook bug

[Leo <sdl.web@gmail.com>]

The definition of eshell-cmpl-load-hook includes eshell-cmpl-initialize,
which is ignored if user has something like:

  (add-hook 'eshell-cmpl-load-hook ...) in their .emacs.

And without eshell-cmpl-initialize, TAB in eshell inserts the TAB char
instead of completing commands, rendering the shell broken.

I think this is a bug. If eshell-cmpl-initialize must be called, please
move it to the right place. It seems to me it is unsafe putting it in
eshell-cmpl-load-hook.

BTW, although I've found eshell very powerful and used it daily, sadly
it is also buggy. I have learnt to ignore most of them. For example,
sometimes when I hit TAB the eshell buffer suddenly disappears and the
completion window is shown instead. Sometimes when I use mouse to scroll
down the completion window brought up by eshell, it disappears too.
