bug#19323: 24.4; Can't reload image files in OS X 10.10.1

[Anthony Cowley]

--text follows this line--

Reloading a PNG image file with C-x v doesn't actually reload the image
file. I originally encountered this trying to use image-flush and
clear-image-cache, but the problem persists with the simple example of
loading an image file after starting with -Q.

C-x v is the prefix for vc-mode.  Why should that reload an image?

This is fixed in trunk, see
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=18918.

I might backport the fix to the emacs-24 branch.

bug#19323: 24.4; Can't reload image files in OS X 10.10.1

[Anthony Cowley]

Ah, thank you! Of course I meant C-x C-v to refresh the file, sorry
for the mixup. A backport would certainly be appreciated.

Thanks again,
Anthony
