Currently PS files are handled by DocView, but there is the same problem
for .xbm/.xpm files that use c-mode.
> Can someone figure out how to to do that?
The problem is in `(use-local-map image-mode-text-map)'.
After switching to "text" mode, it sets the local map to
image-mode-text-map with a single key binding `C-c C-c'
instead of restoring the original map of the major mode.
The following patch fixes this bug. It saves a copy of the original
map to the internal buffer-local variable `image-mode-local-map'
with the additional image-mode specific key binding `C-c C-c' to
switch back to the image mode. And on switching to the text mode
restores the original major mode map from this variable.
