Remove an opinionated section on "What Eshell is not"

I don't find this information to accurately reflect possible use cases
for Eshell; plus, it doesn't offer much in the way of information,
just opinion.

-
-Eshell is @emph{not} a replacement for system shells such as
-@command{bash} or @command{zsh}.  Use Eshell when you want to move
-text between Emacs and external processes; if you only want to pipe
-output from one external process to another (and then another, and so
-on), use a system shell, because Emacs's IO system is buffer oriented,
-not stream oriented, and is very inefficient at such tasks.  If you
-want to write shell scripts in Eshell, don't; either write an elisp
-library or use a system shell.
-
-Some things Eshell just doesn't do well.  It fills the niche between
-IELM and your system shell, where the peculiar use-cases lie, and it
-is less than ideal outside that niche.
