Truncate the eshell buffer when it gets larger than
=eshell-buffer-maximum-lines= number of lines. For some reason I have
to use the =eshell-load-hook= instead of just relying on ~eshell.el~
and ~esh-mode.el~ being loaded because it seems that
=with-eval-after-load= loads this file before ~eshell.el~ is actually
loaded.
