Handle lines with \n symbols in result sets about ejc-sql

[stardiviner]

I guess my error output is associated with this issue.

When I show last result [C-c e up]. I got error (I toggled toggle-debug-on-error):

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  string-match("\n" nil 0)
  split-string(nil "\n")
  (let ((result-lines (split-string result "\n"))) (message "%s" (if (<= (length result-lines) 3) (apply 'concat (cl-subseq result-lines 0 3)) (concat (apply 'concat (cl-subseq result-lines 0 3)) "... (" (number-to-string (- (length result-lines) 3)) " more)"))))
  (if ejc-show-results-buffer (let ((output-buffer (ejc-get-output-buffer)) (old-split split-width-threshold)) (set-buffer output-buffer) (if result (progn (read-only-mode -1) (erase-buffer) (insert result))) (read-only-mode 1) (beginning-of-buffer) (setq split-width-threshold nil) (display-buffer output-buffer) (setq split-width-threshold old-split)) (let ((result-lines (split-string result "\n"))) (message "%s" (if (<= (length result-lines) 3) (apply 'concat (cl-subseq result-lines 0 3)) (concat (apply 'concat (cl-subseq result-lines 0 3)) "...

@stardiviner, this problem is not related to the issue, but I guess it's fixed by the following commit: a4db6db
