Bug fix for eshell-remote-command in lisp/eshell/esh-ext.el

[Colin Williams <lackita@gmail.com>]

The function shell-command will sometimes split the current frame to
display the output.  This means that even though eshell-remote-command
kills the buffer in question, the window layout has been altered.  I
suggest changing

	  (setq exitcode
	           (funcall handler 'shell-command
			       (mapconcat 'shell-quote-argument
				                 (append (list command) args) " ")
		   outbuf errbuf))

to

	  (setq exitcode
		(save-window-excursion
		  (funcall handler 'shell-command
			   (mapconcat 'shell-quote-argument
				      (append (list command) args) " ")
			   outbuf errbuf)))

which will fix any mucking around with the frames window configuration
that shell-command decides to do.

This is my first bug fix for a gnu project, so if you need me to
provide a diff for this change, let me know.
