Then I'd have to make doc-view-mode a minor mode, right?  Are there
other benefits except that you get font-locking for PS files then?

Currently I don't have too much time to work on this, but I'll put it on

I like `q' to be bound to bury-buffer, but I agree that rebinding `C-x
k' isn't perfect and I'll take it out.

Right.  But since I implemented this mode-line-process indicator, those
messages are superfluous anyway and I'll take them out.
