Hi Alan & Drew,
I've made some changes:
- I enhanced the docstring to mention what doc-view actually is.
- If the file doesn't exist or is empty, then we fallback to ps-mode
or fundamental-mode, depending on the file name extension
- If the images cannot be displayed (no png support, missing
conversion utility, tty frame), then the message is more explicit.
Now it says to which mode C-c C-c would switch, the C-c C-t message
was enhanced according to Alan's suggestion and it mentions `k'
which kills the buffer and stops a possibly running conversion.
