Re: doc-view compilation warnings

[Richard Stallman]

    The only thing that remains is to find another keybinding for toggling
    between editing and viewing with doc-view, because ps-mode already uses
    `C-c C-c'.  Suggestions?

C-c C-c is good for this, for consistency with Image mode.
So maybe ps-mode should change its C-c C-c binding to something else.
Any suggestions for what to change it to?

ps-mode also has a C-c v binding, which violates the Emacs conventions
for major modes, so that should be changed (or just deleted).
