Comment (by SergeyBiryukov):

 It gets weirder :)

 * The initial list from the ticket description is what I get after running
 the `precommit:image` task on Windows 10.
 * Despite SVN reporting binary file differences, there are actually no
 differences when comparing the file contents.
 * The only actual difference for me is `src/wp-admin/images/loading.gif`,
 which keeps changing size between 1373 and 1369 bytes.
 * At one point I also got differences in `src/wp-
 includes/images/smilies/icon_redface.gif` changing between 645 and 641
 bytes, but it's not as consistent as `loading.gif`. This is still on
 Windows 10.
 * When running `npm run grunt precommit:image` on a Git checkout on Ubuntu
 18.04 LTS, this is the list I get:
 {{{
 src/wp-admin/images/loading.gif
 src/wp-admin/images/media-button-image.gif
 src/wp-admin/images/media-button-video.gif
 src/wp-admin/images/wpspin_light-2x.gif
 src/wp-admin/images/wpspin_light.gif
 src/wp-includes/images/smilies/icon_redface.gif
 src/wp-includes/images/wpspin-2x.gif
 src/wp-includes/images/wpspin.gif
 }}}
  Again, no actual differences in file contents, just Git reporting binary
 file changes.
