On machines where MAIL_USE_FLOCK is true, movemail truncates
/usr/spool/mail/$USER rather than deleting it.  Unfortunately,
rmail-insert-inbox-text will append a newline to the RMAIL buffer
whenever the file exists, not only if it is nonempty.  This causes
the problem that the G command marks the buffer as modified even
if no mail was found, leading to unnecessary saving of the RMAIL
file.  The fix is to replace the lines:

	  (progn (goto-char (point-max))
		 (insert-file-contents tofile)
		 (goto-char (point-max))
		 (or (= (preceding-char) ?\n)
		     (insert ?\n))

with:

	  (progn (goto-char (point-max))
		 (or (zerop (nth 1 (insert-file-contents tofile)))
		     (progn
		       (goto-char (point-max))
		       (or (= (preceding-char) ?\n)
			   (insert ?\n))))

in rmail-insert-inbox-text.
