30 | ;;; This is Sebastian Kremer's excellent dired-x.el (Dired Extra), version |
| 31 | ;;; 1.191, hacked up for GNU Emacs 19. Redundant or conflicting material | |
| 32 | ;;; has been removed or renamed in order to work properly with dired of | |
| 33 | ;;; GNU Emacs 19. All suggestions or comments are most welcomed. | |

58 | ;;; CAUTION: If you are using a version of GNU Emacs earlier than 19.20 than |
| 59 | ;;; you may have to edit dired.el. The copy of dired.el in GNU Emacs versions | |
| 60 | ;;; earlier than 19.20 incorrectly had the call to run-hooks *before* the call | |
| 61 | ;;; to provide. In such a case, it is possible that byte-compiling and/or | |
| 62 | ;;; loading dired can cause an infinite loop. To prevent this, make sure the | |
| 63 | ;;; line of code | |
| 64 | ;;; | |
| 65 | ;;; (run-hooks 'dired-load-hook) | |
| 66 | ;;; | |
| 67 | ;;; is the *last* executable line in the file dired.el. That is, make sure it | |
| 68 | ;;; comes *after* the line | |
