Fix out of boundary access with exif (#617)
* Fix out of boundary access The while-loop is not finished when pos is set to EXIF_MAX_DATA. Instead, the loop continues and therefore tries to access data outside of the array. This is triggered when compiled with exif=1 and asan: $ feh --draw-exif image.jpg * Fixed formatting No functional change but makes previous commit easier verifiable (independent of tab space setup). * Call break; instead of setting pos2 to a magic value This is in line with the following else clause * Another cosmetic adjustment Co-authored-by: Daniel Friesel <derf@finalrewind.org>
