[split] CI3.1.0 image library broken

The image library has been broken when using Imagemagik since version 3.1.0. I've reported this twice now.

https://github.com/bcit-ci/CodeIgniter/issues/4902

I managed to fix the Image_lib.php by adding a space:

CodeIgniter-3.1.2/system/libraries/Image_lib.php
// about line 888

PHP Code:

# John_Betong ADDED LEADING SPACE - 2016-11-05
  $cmd .= ' ' .escapeshellarg($this->full_src_path) .' '.escapeshellarg($this->full_dst_path).' 2>&1'; 


Edit:
Problem was no space after the image dimensions:

/* # ORIGINAL HAS MISSING LEADING SPACE
 $cmd .= escapeshellarg($this->full_src_path).' '.escapeshellarg($this->full_dst_path).' 2>&1';

 $cmd = '
 /etc/alternatives/convert
  -quality 84
  -resize 128x100'/home/john-betong/www/afiles/images/douglas-adams-happy-towel-day.jpg'
 '/home/john-betong/www/thumb/douglas-adams-happy-towel-day_thumb.jpg' 2>&1'
;

*/

Yes I know I included the proper fix in both of the GitHub issues I opened. Thanks for posting it here in case others run into it and don't check the repo.

I tried this method but doesn't work for me. Finnaly I switched back to CI 3.1.0. Sad
